Today I had my new Rock Island GI compact at the range for the second time. First time out it had 1 fte out of 50 rounds of Federal ball, leaving the brass halfway in the chamber. Today I had 5 fte out of 70 rounds with Win WB and PMC ball, all being the last round in both the RIA suplied ACT mag and a brand new Wilson Combat mag. All rounds were jammed into the top of the mag with the slide locked back normally.
As you can see, the brass is jammed into the top of the mag and the front end is damaged from either the barrel or the slide. (sorry for poor cell phone pic)
The brass was even dinged up in some that ejected normally.
I noticed when I first stripped and cleaned the pistol that the extractor is rotated a bit from where it probably should be.
This is where the extractor ends up after the firing pin retainer is installed even if I straighten the extractor first. I also noticed brass marks in front of the ejection port on the slide. Brass was ejecting in every direction, some landing 6 feet away at 1:00!
To me this looks like an extractor problem except for the fact that it was always the last round in the mag. I also can't figure out how it damages the front end of the case and still locks back the slide normally and why it would jam the empty brass back into the top of the mag. It even bent the top of the new Wilson mag.
Any thoughts? I really wanted this to be my EDC after I get a few hundred rounds through it. My full size Rock Island has been faultless in 1000 rounds and I know compacts can be finicky but?!
Update: 9-18
I checked the extractor tension, seems OK. Definitely not too loose. Removed the extractor and checked for missalignment between the retainer slot and the end of the extractor. Again everything looks good. Then removed the retainer and extractor from my full size to do some comparison. While all the parts appear identical the full size extractor was too tight to fit in the compact. In the end I managed to re install the extractor and get it clocked correctly. The Retainer and extractor are VERY tight so the extractor rotating during use is probably not happening.
I will try to get some range time in this weekend and see what happens.
