Something is definitely wrong. Put 100 rounds thru it (Winchester white box) yesterday to total 350, along with 200 rounds thru my P220 that has yet to hiccup in the 350 rounds I've put thru it since I got it. The M9 is very random...during the session, sometimes it would eat up 3 full magazines without a problem, other times it would jam 5 times in one mag but not the other mag, and other times it would jam going thru both magazines. It seems to pull the casing about halfway out of the chamber and then let go, or maybe the casing just moves half way out from the recoil energy. I thought maybe the chamber was too tight, but that's not it; I field stripped it and slipped a round into the chamber and it was plenty loose. Maybe it's a loose extractor spring? The hook moves if I push on it hard enough, but maybe it needs more pressure. I'll contact Steyr tomorrow to discuss the problem. If it's as simple as a loose extractor, the fix should be quick and painless and I can go on having a happy Steyr.
