(.45) They seem to hang up at the bottom of the feed ramp almost every shot. I can retract the slide slightly, let it go, and they will feed. When I got home from the range, I polished the ramp, but haven't had a chance to try it again since. Ball and EFMJ's feed perfectly. The pistol has only about 100-150 rounds through it - might it just need more break-in? Anyone else had this problem? Thanks.
