Ruger 22/45 MK. III Feed Problems
Ruger 22/45 Mk. III .22 Semi-Auto PistolI purchased a Mk III 22/45 and am experiencing feeding problems. The first 3 or 4 rounds that are loaded, sit up at the correct angle for flawless feeding. With the following rounds, the nose of the bullet sits too low to clear the edge of the feed ramp, which is where they hang up. I sent the magazines back to Ruger and they sent me 2 replacements. I still experience problems. I have tried a variety of ammo. Any suggestions?? I wish that I hadn't sold my Mk II 22/45. Never had a problem out of it.I don't have a MK. III version of the 22/45 to play with, so I don't have any first hand experience with this problem. Generally speaking, if you can drop the magazine out of the gun and the rounds stay down inside, it's a problem with the magazine. Different ammo can make quite a difference as the overall length of the cartridge and the shape of the bullet nose varies quite a bit from one brand to another.
If it's feeding the round either against the feed ramp and stopping, the magazine lips may be very slightly too close together. It's better to try several magazines and hopefully find one that feeds OK, them carefully measure the distance between the lips and bend the non-working mags to match. Sometimes too tight will act like they are too loose, so matching up to a working magazine is the best way to go.
Also, brand new semi-auto pistols often have feed problems until they are either carefully smoothed and polished internally, or several thousands of rounds are put through them. This all assumes that the pistol is clean and properly lubricated, though. Yes, I know they are a pain to get back together, but if you clean it regularly it gets fairly easy to reassemble.
Anyhow, I'm throwing the question out to you all in cyber-gunnie land to see if any of you have had the same problem, and if so, what did you do to solve it?

I haven't noticed the problem with my Mk.III Hunter 22/45. It feeds pretty flawlessly. I also have a Mk.II 50th Anniversary Edition, that I've had for six years or so. Any time I've had a feeding issue, it's been either ammo or dirty action.
I'll see if I can take a moment later and try to reproduce the problem with one of my MkIII mags.
I'm not sure what he means by sit up or down. As long as it clears through the notch in the front of the mag, it doesn't much matter. If it's getting stuck not clearing the notch, it's definitely a bad mag. If it clears the notch, the spring forces it up when it clears about halfway through the magazine, which puts the cartridge in place on the bolt face to get shoved into the chamber.
It could be the magazine is sitting too low perhaps, perhaps because of not being locked in all the way. I actually hate that Ruger didn't make the Mk.III magazine drop free. On the old Mk.II, it was easy to tell if your magazine wasn't locked in, because you could visually see it. On the Mk.III, it's tough to tell sometimes.
One thing I will say, though, is the guns don't always come from the factory as clean and well lubricated as one might think. My 10/22 had ejection problems quite a bit straight out of the factory. Stripped it down and cleaned it, re-oiled, then never had a problem again. This doesn't sound like one of those cases, but it couldn't hurt. The Mk.III is tough to tear down and reassemble, just to warn.
First thing I'd do is tear down the magazine; lightly lubricate the inside, spring @ follower with Breakfree, then wipe dry. If cleaning and lubing the magazine doesn't do the trick, then I'd use a buffing wheel on a Dremel tool (without any compound) and polish the feed ramp.
I have a 22/45 Mark III and am experiencing exactly the same problem, as did a friend of mine. I tried smoothing the leading edge of the feed ramp, which has not helped. My next step is to purchase some fmj ammo to see if it handles the situation any better. I'm going to say that the mags are good to go. This is the only weapon I've owned or used which has experienced this problem so consistently. I will not purchase another Ruger, based on this experience.
My 22/45 (bought new) has gone through a brick of lead nose ammo (and a random selection of other) with no problems at all. The other two larger caliber semi-autos I have from them are also flawless in their actions.
That being said, if I felt I'd done everything possible to find a cause/correct the issue I'd send it back to them with a firm but polite letter asking them to fix their product. Document the issue including all the trouble you've gone through and what ammo type/brand you've tried, and provide them with a phone number they can call (encourage them to) if they have questions. I've only had to return one handgun to Ruger and that was an SP-101 I bought used from a pawn shop. It was returned in perfect working order less than two weeks later.
I had somewhat similar issues with a Ruger Mark II. One of the factory mags that came with the gun functioned fine, the other one didn't. I cleaned the gun multiple times and used different varieties of ammo. HP rounds would sometimes hang in the one magazine.
What finally resolved the issue was cleaning the magazine, particularly under the magazine feed lips. There was a done of built up powder and gunk under there.
Hope this helps.
Change ammo. I tried the expensive CCI Stingers, and they didn't feed worth sh!t. The cheap Remington Golden Bullets or Federals that you can get in the 550 pack at Wal-Mart feed flawlessly for me.
Granted, the bulk packs seem to have a higher percentage of duds than the more expensive brands, but if you can't feed it what's the difference. Besides, duds are perfect to toss back in the mix to test if you're flinching or not.
I have a MKIII Target with the same or similar problem. The rounds are feeding into the bottom lip of the feed ramp and the ramp is actually slicing into the lead nose as the bolt returns. What I have found, is that the mags have a very minute level of vertical play even when fully locked into the pistol. If I press on the bottom of the locked mag, I can get it to move maybe 1/32nd of an inch further up into the pistol. It will feed perfectly as long as I maintain the pressure. Unfortunately, it will not stay in this forced position as this is beyond the magazine lock position. In my opinion, the feed ramp is slightly too short causing the rounds to dig into the feed ramp instead of slide up. Ammo is not the issue, and it seems to have the same issue with all of the mags. I am still looking for a fix...
I have the opposite problem with a 1965 Mark I. I have two brand new magazines (and switched the button to the other side) that feed 2 rounds about every 3rd or 4th shell. The original magazine that came with the pistol never does this, only the new ones. Anyone ever see this before?
I have a ruger mk 111 22 45 > Yes you guessed it feeding problems! There is no cure, Ruger has blundered, & they know it!! > Best ammo TO USE > Federal 550 pack, WITH THUIS AMMO, NO JAMS IN 400 ROUNDS! ALL OTHER BRANDS TOTAL DISASTER!! IT'S A PITY, SUCH A NICE GUN IN THE HAND, WITH A MOST PERMANENT PROBLEM! SHAME ON RUGER!! THEY KNOW BETTER!! RECALL PEOPLE!! > YOU BET!!
I have a ruger MK III target model and it is jambing. But my problem seems slightly different. My problem is shells aren't being ejected correctly. They dont exit the camber completely and jambs as the next round is loaded. I have cleaned and oiled the gun. My dad has cleaned and oiled it. We have even taken it to a gunsmith for cleaning and oiling. We have tried almost every type of ammo. We have bought new clips. Nothing seems to work. Any ideas?
ANON: If it was mine I'd polish the chamber to make sure the rounds drop in freely and won't hang up on the way out. Then I'd replace the extractor and extractor spring. Make sure the extractor isn't hanging up on a burr or anything so it can get a full grip on the rim. You might also consider a Volquartsen extractor, they are a bit more expensive but probably worth it.
Mr. C.
I have a 22/45 MK III. I've put something like 1200 rounds through it with only one FTE and that was most likely due to me trying to shoot with my off hand and not having a proper grip. I've fed it about equal amounts of CCI and Federal ammo, mostly hollow point. I have noticed on mine that the magazines don't always lock into place easily. I sometimes have to push it fairly hard with my thumb to get it the last little bit of the way into the handle and lock it into place. I don't know if it's related to the problem or not, but I thought I'd throw it out there just in case.
Try rubbing the wax off the nose of the bullet, only takes a couple of swipes to get a shiny lead nose. Some mags or bullet lengths are tight and the wax binds the bullet from lifting with the other gunk in there - cheap soloution if it makes it work.
I believe its a combination of the three (Magazines,feed ramp, and not locking in place) does any one out there have the Knowledge and bravery to attempt a fix it on there own....i am pretty giving up on even taking it out to plink I think it is a accurate gun when you not dealing with these problems....
Having feeding problems with your mark 2 or 3 go to the link below, it explained it all for me. I have no more issues, Feeding flawlessly now
http://xavierthoughts.blogspot.com/2008/10/mkii-magazine-tweak.html
Same feeding problems for me. The top round is gripped firmly by the magazine at the primer end, but the bullet end is free to swing up and down a significant amount. If it is 'nose down', it gets caught on the feed ramp. Also noticed very gummy feeding of the stack (400 rounds of CMP Aguila fired), so I think I need to disassemble, clean and lube the mags, and try again. I've been looking for some extended bump pads for the mags to address the fully seated issue, but have yet to find anything manufactured. Looks like adapting some other pad that is close enough in fit and attaching with epoxy or machine screws will be the way to go.
use electric contact cleaner to "wash out" the pistol. then, as with ANY .22 cal. auto pistol it's AMMO-AMMO-AMMO. Round nose solids-no wax or lube-try several brands until you find what your MK II or MK III likes, and you'll be pleased at the results !!!
I had the same problem. And like ANON said- AMMO AMMO AMMO! I was using Win x pert lead, hp. The lead is so soft, it catches the ramp every 3 or 4 rounds. I switched back to the CCI hp jacketed rounds and haven't had a problem since. I love this pistol, and now that I feed her the right ammo, she loves me back.
Purchased new MK3 P512. Constant feed and jamming problems. Can't get the a sibgle magazine without problems. I sent the gun back to Ruger and asked them not to return it till they could run 100 rounds without error. We'll se how it comes back. If I still have problems I will try the magazine tweak described on the above link. Sounds like many folks have had success with the fix. I agree that Ruger has a problem with this gun and they know it. I was told repairs were going to take 4 to six weeks. Long time witout my new plinker!
Feeding problems occurs for me when I use jacketed hallow points. Try using Federal ammunition. I normally use Premium Champion Value Pack.
I recently purchased a Ruger 22/45 MK III and I've noticed that my magazines need an extra umph to fully insert them into the gun. And I mean EXTRA UMPH! Heres what I do:
-I insert the magazine until it feels like it locks into place (its not locked in yet)
-Then I place my thumb on the bottom of the gun grip - slightly rearward of the middle of the clip base (toward the rear of the gun) and roll/press the magazine further in place.
You'll hear a quiet click that lets you know you've fully locked it in place. I have to apply enough pressure to break a pencil each time I do this to be confident it is fully inserted (and it is annoying.) If you haven't been pressing this hard on your 22/45 you probably haven't be inserting your magazine completely.
-Heres a tip
If you lightly put you're thumb on the mag release button while you insert the magazine you can feel the second click more easily than you can hear it. It jolts the release button when it locks into place.
I hope this helps,
Good luck!
Just picked up a 22/45 MK III for my son. Immediately had problems with the Remmington hollow-point ammo we use for his Marlin rifle... tried standard round-bullets (Blazers, green-dot CCI, and Fiocchi and all work great... just the hollow-points get caught on the bottom lip of the feed...
Yep.
This is a lot of people with the same problem. I hope they recall and fix soon.
1. My magazine doesn't insert fully unless I give it a smack.
2. One failure to load or extract every 150-300 rounds. Never fails.
3. It's the feeding ramp? I let a buddy shoot it. He had a jam. Tried to force it and the ramp immediately chipped.
Why he was trying to force it I don't know. Fool.
Seems like the steel is soft and sharp?
What do you think?
James says, Haveing problems with your Ruger 22/45 jaming or hanging, try useing 22 long rifle Copper-Plated Hollow Point 1640 FPS 32 grain STINGER bullets. Believe me its a varmint bullet but it makes all the good. Thanks James Finley,Charlotte NC.
I have a new MKIII 22/45, and it fails to feed the first round out of the magazine with 4 types of copper plated, hollow point ammo, CCI, Federal, and Winchester. The bullet is driven straight foreward by the bolt into the sharp bottom edge of the feed ramp, which cuts into the bullet and stops it there. I called Ruger and the service person told me I needed to load the magazine so that the first round was "tipped up", which you can do, but that is ludicrous, because you shouldn't have to do that, and also the second round can't be manipulated, and it hangs up after the first one is cycled. The ONLY ammo that works for me is the CCI Small Game Bullet, which is a solid plain lead bullet. Either the magazine is incorrect, is too low relative to the feed ramp, or the feed ramp is too short. There is simply something wrong with the design.
I just used my 22/45 at the range and had tons of trouble until I closed the bolt Then put the magazine in.. In the ruger book it says to keep the bolt pulled all the back and locked and then put in the magazine.. Every time i did this, the gun would jam and not properly insert the bullet in the chamber.. i was using hollow points... any ideas??
thanks,
jim
Has anyone experiencing this issue with the bullets nosing into the feed ramp actually sent their pistol back to Ruger? If so, did you get it back in working condition? I am having the exact same issue (Bullets nosing into feed ramp on just about all brands/types). I can't get the Federal 550 pack ammo around here any more, so I'm now stuck with a pistol that I have to use in single shot mode. Pretty embarassing at the range! I E-Mailed Ruger and they said to send the pistol back so they can "examine it". They gave no indication that they knew what is going on with this pistol, which I find hard to believe. I firmly believe it is an issue with the magazines - load one round of any brand/type and it will never jam - put in more than one round and then it's jam city. I was just wondering if it is even worth sending my pistol back to Ruger or if I will just get the "we could not re-create your problem" response from them
I've had my MKIII 22/45 for almost two years now. As soon as I got it, I noticed the feeding issue. It was my first new gun, so I assumed I just had some breaking in to do. About three weeks after I got the gun, the bolt got jammed stuck. I took it to the shop I bought it from and they couldn't get it apart. I had to pay $30 to ship it to Ruger after just paying quite a bit for it. It came back with a note that said I had tried to take it apart and put it back together and that they had re-assembled it correctly, which I hadn't. Everything's worked good since I got it back, but the bullets still ram into the feed ramp. Unfortunately I don't get the chance to use it enough to justify taking it to a gunsmith to look at it. I'm going to try the mod in the above link to see what I can do. If it doesn't work, I may get on the phone with Ruger to see what I can do.
CCI hollow points dont load correctly. They get slammed into the feeder in half.
I called Ruger. They said hollow points do work. Try another ammo. Then said something interesting: They had similar issue with another gun had to redesign magazine longer.
Remington solid points work.
I had mis feeding problems with my 22/45 right out of the box. I had two friends shooting 22/45's at the same time using the same ammo and neither one had problems. The manual said disassemble and clean which I did and still had the same problem. I sent it to Ruger they had it for 8 weeks and sent it back after taking it apart and inspecting it. Same problem with mis feeds. my buddies guns feeds fine mine sucks. I not sure what I'm going to do with it now. I sent 2 pages of detailed info on the history of misfeeds. 4 different mags, 6 different ammos, 3 different shooters etc...etc... In return I asked for a call before shipping the gun back. No call from Ruger only a gun that doesn't work right. I'm pissed
Ruger seems to have a policy of corporate denial when it comes to this feeding issue. You explain to them exactly what is happening and there is no acknowledgement on their part! You get silence or a non-acknowledgement type of answer from them. This seems to be what everyone is experiencing from them. Totally unbelievable!
On the 22/45 mark 3 feed and eject problems: The rear lips of the magazine sometimes strike the spent casing and make it eject prematurely. The magazine is a ruger problem but if you will do GoldenLoki's magazine tweak it will fix that for good. I also put a Volquartsen Exact Edge extractor on mine and it holds the spent casing much more tightly, but zI think the magazine tweak is all you need. Recommend insert the full mag. with the bolt open. My 22/45 mk3 feeds and ejects anything now - bulk ammo, round nose winchester, Aguila SSS, wide nosed hollow points, flat nose truncated, you name it. But the most accurate for me without going to high-priced ammo is either CCI mini-mags or Aguila Super Extra.
Correction to my previous post . . . the magazine mod is not from GoldenLoki. It's here: http://xavierthoughts.blogspot.com/2008/10/mkii-magazine-tweak.html
Ruger Mark II or Mark III this WILL fix your feed/eject issues!
I have a Ruger 22/45 Mark III that performed flawlessly with the first box of Federal in the 550 bulk pack. Today after feeding 75 or so Federals I started using the Winchester Super X22 Long Rifle Hollow point plated bullets. As the mag was inserted and the bolt released the trigger felt as if the safety was on but is was not and the ammo would not feed. Anyone else have this problem. The gun was clean.
Ruger needs to tell people up front that this pistol will only function with certain ammunition brands/types! Marlin does this in their 795 owner's manual.
People are discovering this aggravating problem the hard way - AFTER they purchase the pistol. Given the ammo climate today, I'm sure most people would not want to purchase a pistol that will only function with 2 or 3 ammo brands/types (and the brands/types that are pretty much impossible to find now).
Really this is an easy fix. The ammo issue is fixed by the tighter Volquartsen extractor. But often just tweaking the magazines a little bit will fix it. The left rear feed lip is too high and is in the way of the spent case if the extractor happens to not have a good tight hold on it. The mag tweak is easy. Look at the following link, and it a link to take you to the mag tweak. I've done 10 magazines, 5 mkII and 5 mkIII 22/45 and they all shoot anything I put in them. http://www.calguns.net/calgunforum/showthread.php?t=204888
Here's two different pages that show what to do. It works. I like the xavier blog the best because it's the easiest. All you need is a dremel too and some fine sandpaper.

I have also experienced the feed ramp jam problem with a new MKIII hunter. This is for bullets that feed flawlessly in an older MKII.
I found that the newer Ruger mags have a deeper cut at the mouth.
I have posted a couple of pictures here:
http://www.prestonsdocsonline.com
A friend of mine used a TIG to add a little metal at the mouth of one of my mags. Now at least I have one mag that now feeds any bullet I have put in it.
The magazine tweaks are correct for many of the stovepipe issues, but I believe the feed problems are a separate issue with the mags.
The response from the Ruger tech was "So what do you want me to do about it?" Great...
Same story...the feed ramp bites just about any type of ammo I try - both round tip and hollow point.
The dealer I bought it from said to call Ruger...didn't want to bother with looking at it. I'm calling Ruger on Monday. I'm definitely finding a new dealer, and depending on Ruger's response...I might be finding another gun company to support.
I have a new 22/45 that would run perfect one time out then would jam a lot the next time out. I found that my problem was in how the magazine was loaded in the gun. If you push the magazine in with your left hand thumb you have a tendency to pust up and toward the rear of the gun.Even if you try to push straight up you still have trouble getting the magazine to seat. When you insert the magazine push up and pull the base of the magazine towrd the front of the pistol. You will hear it lock into place with a snap. Once I started doing this I never had another jam or feeding problem
I never followed up on my post. Ruger gave me a hard time and told me they weren't going to repair it because "the feed ramp had been altered." I asked them why someone would even alter a feeding ramp, and their chief tech said that she didn't know but someone had altered it. I told her I bought the gun new and that the paperwork was included with everything she had...and that the dealer wouldn't even look at it. She said she would fix it "just this once" (like I was just going to get a slap on the wrist for whatever bad thing I had done). I got a bit mad at the insinuation and the way I was being treated, and explained to her that between her and the dealer I was being left holding the bag...buying a brand new gun that was problematic. She also dismissed my claims that others have had the same problem as I've seen in several gun forums.
In summary...Ruger's tech support was rude and made an accusation that I had purposely done something to the feeding ramp for whatever reason.
In response to "Anonymous": my issue had nothing to do with the way the mag was loaded. Even the experienced people at Ruger couldn't get my gun to feed properly. The feeding ramp would bite every bullet that went through...either jamming it or shaving off part of the bullet.
Yes! With my 22/45 MKIII the magazine can't simply be inserted normally like a normal gun. Has to be pushed forward to hear it "lock". I insert the magazine fully, then use the heel of my hand, and push on the back corner of the magazine to force it forward until it clicks. If there is no click, then there is no lock and I can simply pull the magazine out without using the mag release. And while firing, the magazine is then liable to work itself loose, causing rounds to get stuck at the bottom edge of the feed ramp.
I cleaned the magazines. Took them apart, very easy to do. After reassembly, I had no malfunctions other than an occassional first round on a full magazine.
I have a Mk III that jams every second or third shot. I watched the extraction, noticing many expended shells getting caught between the activator for the "loaded" indicator and the bottom of the chamber. That stupid chamber indicator can be pushed out from the inside and...duct taped permanently "loaded". When I do this the gun will NOT jam no matter the ammo. Now I have to find a way to get rid of the internal part of the "indicator" that screwed up one of our best guns...
Same problem with my new Mk III as long as I only load 2 or 3 cartriges in a magazine they sit nose up and feed properly if I load a mag full the first round sits nose down and will not feed. Everyone told me this was the best plinking pistol to buy. I'm very dissapointed. I also bought a High Point JCP 40 S&W, Paid about half what I did for the Ruger and had no problems with the so called "junk gun"
Update of my comment of May 1st! After reading a ton of forum comments on this problem I decided to try some different ammo, I had initially tried bulk pack Winchester Xpert22 36gr hollow points so I went to Walley World and picked up a 550 round Value Pack of Federal copper plated 36gr hollow points took the pistol and the Federal ammo out to the range and ran over 200 rounds through the gun without one single problem. I mean No Problem At All! None! So my advise to anyone who has FTF or FTE problems to try the Federal ammo that Walley World sells, you just might fix your problem and fall in love again like I did!
I bought a nice used MKII recently that had two problems that i was able to fix. One the chamber release lever was so hard to push it was painful and the other was jamming rounds.
First fix was a light filing to clean and slightly angle the release mechanism, polish and lube it. I did it one stroke at a time until i liked the feel.
On the jamming rounds I eased the back ears on the magazine like mentioned by a previous post and tapped with a light hammer the front ears until I could bend them in just slight enough to touch but not drag on the bullet.
As I slowly checked how the bullet was being pushed forward it would jump out of the magazine too soon and bounce high and above the barrel often enough to crease the lead and prevent entrance.
I think I've got it just right as I have gone through a number of different rounds and all went through with no jams. I'll try more tomorrow.
I just purchased the MarkIII 22/45 and had the same problems. I have a S&W Model41 and it is flawless. When loading the Mag. it would pop out after the first round. If you put the Mag. in with a slap so the first so it would stay in the first round would jam. I took about .020 to .030 off the surface were the bottom of the mag. contacts the fram and the problem is solved. I have put 250 to 300 rounds through the gun without one malfunction. Ruger needs to do a 100% QC check on this before the guns are shipped. The Steel fram Mark III do not have the same problem. This fix some how fixed the problem of the Mag. having to be pulled out on five of my Mags.
I had the same problem and about 98% of the time it is the mags. I had five mags with that same problem, fixed it in 15 minutes and never jammed again. on the top of the mag, where you load the bullets,, there is a v notch between feed lips. These form a sharp point. Round them off with a dremel and its done. Never had a jam again. There are pictures on the web somewhere for it.
bigstick0000 is right on target with the magazine mod. The empty cartridge will sometimes hit the left rear feed lip and come loose from the extractor before it goes back to hit the ejector. The link to an article about how to do this follows. You will not need a new extractor unless yours is just plain not working right. link here: http://xavierthoughts.blogspot.com/2008/10/mkii-magazine-tweak.html
I bought a new Mark III target gun a few weeks ago and experienced extraction problems right away. I was using Winchester Xpert HV 36 grain lead nosed hollow points. Lots of duds too!
Today I went back to the range. I used Winchester copper plated 36 grain in 555 bulk pack from Wallyworld. Not one extraction problem. Only a few duds.
I'm feeling more optimistic about the gun now.
Good luck. I sense the frustration of Mark III users out there.
Nice to know I'm not alone.
It seems as though those that have not had this problem are not grasping the high low key. I have had mine for a few years and only recently started getting it. I have the Mark III as well and have mostly shot the Wally World Remington hollowpoint. Recently I picked up a brick of Winchester and the problem occured. Please note I shoot plenty of Winchester in other calibers and have always had very good result. I'm just saying I had not tried the 22lr hp by Winchester until recently. I am definately not a Winchester or Ruger hater, every other Ruger I have owned was more forgiving of ammo than all my brownings, rock river, or sig by far.
What the feed problem is, is that due to the fact that it is a rim fire cartridge, there is slop up and down between rounds. When mine mis-fed, it was because the front of the round was canted down and would impale itself on the bottom of the feed ramp. This would typically happen on the first round if you fed the round with the bolt closed and did not ensure it was elevated in the mag before inserting. It would occur on random rounds likewise. I did find that it would help if I racked the mag against my hand or something towards the back top of the mag as you would commonly do with a GI AR mag.
Just thought I'd explain the symptoms a bit better for those that have not experienced it. But I can concur that it can happen on a well maintained previously perfectly functioning Mark III.
Well guys if you want to know what the problem is, here it is. I know because I have a mark 111 and our range has 5 of them, all 2245s. I work at a public range and see the problem all the time. The magazines are very difficult to seat. Seat them at slide lock. I use my 2245 in Ruger Rimfire matches, but have sanded down the base pads so they will seat easily and lock into place. Problem Solved!
my brand new 22/45 Black-Lite has this problem. magazines will not fully seat and lock unless i push rear of magazine's base-pad forward (with either factory magazines).
the thread below appears to point to one of the more likely problems in my case: the frame having incorrect dimensions and needed light sanding/filing-
http://www.guntalk-online.com/forum/viewtopic.php?t=3195&sid=b13509f67376c4d4f9dccc05249ae7dd
To anyone experiencing feed issues make sure that your mag is fully inserted. If the mag release button has not returned flush to the right hand side of the grip the mag is not fully inserted. A push on the rear bottom of the mag should seat it fully.
Okay, people not having a problem with their 22/45 Mk IIIs - they are lucky. I bought mine in 2012 so based on these entries it is not a fluke and Ruger knows but doesn't acknowledge the problem. I tested three different ammo types today and in the case of the Remington Gold solid bullet never had a problem. All hollow points types and Thunderbolts would jam on the first cycle of the gun, period. The feed ramp is too sharp and literally cut the bullets in a fashion that wont feed in nearly any other 22 I own. My magazines are clean, seated properly as I load them all the same but get a different result, so it is based on ammo type and the gun's inability to handle a variety. So I will shoot the ammo that works and think that Ruger should acknowledge the flaw. Period.
I purchased my Ruger Mark III 22/45 in 2008 and had feeding problems from day one. Any hollow point ammo I used stuck on the feed ram, regular solid point fed perfectly. I'm glad I'm not the only one experiencing this problem. I will add, I have purchased five guns since then; none of them RUGERS!
I purchased a Ruger mkIII Lite on 7/19/2014 and took it straight to the range. I had CCI Match, Federal Match and Remington Gold. The first round loaded into the weapon failed to load. After recycling, it fed and had 3 misfires and ejection issues. Same for the second mag.
I reloaded with CCI Match with again did not feed the first round. It also failed to eject then double loaded a round while the fired casing was in the chamber. It even came to the point 2 times of using a knife to remove the brass. After loading 2 10 round mags of CCI Match, the weapon was charged, trigger pulled, fired, but failed to eject. the action had to be manually worked for 6 rounds, I changed magazines and this happened 4 more times. I gave up and carried it back to the retailer I purchased it from....
The weapon is nothing like the other weapons Ive purchased from Ruger... Very disappointing
I'm having this issue with a mkIII Competition model. Six magazines and I get the failure to feed due to the bullet nose splitting on the edge of the feed ramp with all six mags. I'm at a loss. I've tried several types of ammo and some are better than others, but they all do it. The magazines are completely inserted. It ejects fine even though the extractor is so crappy that it will not extract a loaded round more than about 1/4"
`I now have 2 Ruger MKIII bull barrel pistols with the non removal-able grips. Both jam with any type of ammo I've tried. I've cleaned, oiled etc. It looks like the rounds don't sit in the magazine at the correct angle. Looks like this has been going on for years by looking at this forum. Just thought I would leave another complaint & then see if social media gets any better response out of Ruger.
