I have a Series 80 Commander that isn't going completely into battery every time. The bullet is starting to enter the chamber but doesn't quite make it. Sometimes once, maybe twice in a magazine. No particular order that I've noticed. It is almost new. I ran the magazines in my Series 80 government and no problem. I can run Winchester standard hollowpoints in the Government but not the Commander. The "jamming" or failure to feed or go into battery just intensifies with hollowpoints. Any suggestions?
