You the guy for one stop Kahr questions, right?
Brand new CM9 repeats the same stoppage every 50 rounds or so, with ball or hollowpoint: failure to feed that stops the bullet nose right at the base of the feed ramp. The mag won't eject and it resolves with a firm slap on the rear of the slide.
Current round count is 650. 200 Federal 147 HST.
Ditch it?
I like the gun well enough. It's accurate and easy to shoot.
But this ain't good.
Edit: Gun is lubed after each session.
