Oh wow...more heartaches with my second G44...I'm convinced it's got Multiple Personality Disorder...one time it's good, the next time it's terrible...this thing is making me crazy:
Every. Single. Time. I racked the slide to load from a mag today, I got this -
...not riding the slide at all, full travel back and then a quick release of the slide, same thing happened with multiple magazines...okay, probably not a mag issue...
...the bottom rim of the jamming rounds had not yet gone far enough up the breech face to hit the extractor, and there was a 'smiley' dent on the front bottom of each bullet, in exactly the same place on all of them...here's just a couple, from about a dozen feeding jams, before I threw the gun back in my range bag and gave up for the day -
so I'm thinking it's a barrel issue...a closer inspection of the barrel revealed some light damage on the extractor side, although I've never closed the slide on an already-chambered round (shown here with the barrel from my first G44 for comparison, first one still looks smooth, even though it's got a higher round count) -
...anyhow, it's not having a problem with extraction/ejection so I concentrated on the top of the feed ramp, where it transitions into the bottom of the chamber. Pushing a small wooden dowel up it, there seemed to be a very small lip that would 'catch' it every time. Same lip on my first G44, but not as bad as the one jamming. I took a Dremel (GASP!) with a very small wool mandrel and some Flitz to it for a few minutes, definitely feels smoother to get that dowel rod up the ramp and into the chamber now.
Slicked everything up with some DuPont Ceramic Lube.
We'll see what happens tomorrow or Thursday at the range.
