Ruger 22/45 MK. III Feed Problems
I 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?
