Ruger Mark IV 22/45 lite failure to feed

[bgd]

New Mark IV 22/45 lite fails to feed about 2 rounds out of 10. it ejects the fired round but fails to feed round into chamber. I have a picture but don't know how to post it.

Does anyone else have this problem?

Your magazines may need to be tuned. Look at Tandemkross.com and there is an excellent video on tuning your mags. I had to tune mine to get them to work 100%.

Have you lubed the mechanism?

I have lubed it generously with Remington oil. I think it has to do with the magazines. I think I will call Ruger Monday and see what they say.

Google the Tandemkros video as suggested earlier. It'll more than likely fix your issue and keep you from the hassle of possibly shipping the gun back to Ruger.

Could it be ammo related?

My 22/45 heavy won't reliably feed MiniMag JHPs. The nose gets hung up on the bottom of the feed ramp. I could feel a small lip there, and working on smoothing that down has helped, but still not 100%. When I have time I'll either work on it some more or run it by a gunsmith, but for the time being I just shoot other ammo.
