It has a broken extractor after 75 some thousand rounds, which I'd failed to diagnose during major international travel to Czech for EEO and a few other countries. Once replaced that particular gun went to over 150,000 rounds as have most of my CZs (9 of them). The broken extractor was caused by a case failure with match ammo in CZ, the gun had a few issues at that match, but then ran fine after a quick inspection in the safety area. I returned home a few weeks later, did the TLG course and it popped up part way through. Once replaced it was fine.
The S&W on the other hand started rusting before it's first trip to the range, kept in the same safe as the rest of my guns, including my Desert Eagle, which according to the internet, is known for rusting. Yet, it didn't. Once cleaned and lubed the S&W continued to be a problem child, accuracy was ####, trigger was ####, trigger spring broke, extractor broke, mag catch broke. Mags, garbage, but that's because of our 10 round law and the crap mags we get as a result. Rear sight was not centered, striker plunger thing had such bad burrs it would jam. The gun kept rusting. Gun was sent back, new barrel was installed, some sort of surface work was done to the slide, it rusts less now, is slightly more accurate, and still has a sh!t trigger. I keep it because I still get the odd student who insists on wanting one and wants to try it out (so it does get shot very seldomly). I'd rather see them shoot a 5946 or just about anything, but they get what they ask for.
Gen 2 M&Ps aren't much better.
