I have a Ruger PC9 that I am running glock mags in. I have tried factory mags and two different aftermarket mags. Factory ammo in 124 gr and 115 gr, as well as multiple reloads using FMJ, JHP and cast lead RN with W-231, W-572, W-Auto-Comp and VV N-320. With all of these I have gotten anywhere from 7-10% malfunctions, primarily the classic stovepipe. At first I thought it was because I was using a Caldwell brass catcher and the brass was bouncing back. Took the brass catcher off and it made no difference. I am running the carbine stock, except for an optic sight. Any thoughts, suggestions? I am at my wits end and ready to send it back to the factory.
