Lately I've been having a terrible problem with this handgun. It seems everytime I pull the slide back and release it the shell gets caught on the ramp of the barrel that is supposed to guide the shell into place. I know the barrrel was designed after the free floating 1911 barrel but it should lock in when the slide comes back and the ramp should be even with shell almost. however there is about a centimeter gap there. I dunno how describe it any better than that. I'd really appreciate any ideas from anyone with a P89 or 90 they are built the exact same. Thanks.
