Hello guys. I have about 500 rounds in my P-01 and sometimes the slide fails to lock after the last round. It started doing this after I detail stripped the gun and polished some internals. I have tried both of my magazines, the slide stop groove/cut is nice and square, and it seems to occur after 40 or 50 rounds straight. I also have a 13lb main spring (wolf springs), race hammer & rrt trigger (cgw), and a reduced power firing pin spring. Any ideas on whats going on?
On a side note, did not happen with federal 115gr, S&B 115gr, and 115gr reloads.
Did happen with independence 115gr, and pmc 124gr.
