I've owned my Glock 38 for approx 3 weeks and have only shot factory hard ball rounds without any malfuction. I bought 500 brass and same number of Rainer 185 gr H.P. I have loaded approx 200 rounds and was using the bbl (out of the gun) as a go-no-go gauge. I noticed every once in a while a round would hang up without going into the chamber. I checked and noticed a ridge inside the chamber above the feed ramp. It almost appears the feed ramp was already there and the chamber was then cut leaving that ridge above the feed ramp. HELP!!!!!!!!! Someone with a 37 or 38 check your chambers and see if yours has a ridge. Need some advise before I screw up this bbl by polishing the feed ramp. Maybe it's normal for the chamber to be made this way, however these is screwed up to me.
