I had some issues with mine for awhile with extraction/ejection. I was bummed, I hadnt had it that long, though I guess its goin on a year now. I tried cleaning my magazines, different ammo, locking my arms when I shoot, new Colt GI magazines... anything to narrow down the problem.
I didnt oil it enough the first time I cleaned it, (used to cleaning and oiling Mossbergs. Its not the same thing so dont get those confussed, entirely different animals) I thought maybe I messed it up, my issues began shortly after that cleaning.
I found it wasnt a feed issue with the magazines, so I had it bein either extraction or ejection. What was happenin was it would fire and the case would get caught between the ejection opening and the barrel as it was returning to battery with a new round. It would be kinda in a bind and could be difficult to clear sometimes.
I would run ammo through just cycling the action by hand while trying to very closely watchwhat was happening between rounds. I tried to watch while it was being fired too, but its more difficult.
Eventually what I saw was that the round wasnt being pulled free from the extractor, and also noticed sometimes the extractor wasnt even opening enough to grab the rim of the case. The slide would try to slam home without the round being fully seated against the bolt. I had a few "misfires" and other jams.
Before finding this, I was getting ready to take it to a gunsmith.
I pulled the thingy off the back of the slide and pulled the firing pin and extractor. Cleaned and scrubbed everything I could and got all sorts of residue off of it. Put it back together and havent had a problem since! Its been shooting really well, well enough, if it handles another day out without any problems, I'll def consider it for concealed carry! (which I had been putting off because of the issues) I wasnt gonna carry it and put any faith or trust in it if I couldnt make it through a single day of shooting!
