HK USP Compact 9mm with LEM trigger. Got about 72K rounds through her total (LEM trigger put in at about 20K), and only started to have some malfunctions recently when I tried some reloads (I've never shot reloads in it before), went back to factory ammo and it's 100% again. Mag springs and recoil spring swapped out every 15K-20K rounds, extractor spring swapped out about 4K rounds ago (think that was part of the problems I had with the reloads), oh and the nights sights were changed about 4yrs ago as the old ones went dead on me.
