LOL, I wouldn't call them torture tests, but I've run two Beretta's and one Girsan through the 2000 challenge (basically no cleaning and lube for 2000 rounds).
I never had one make it all the way through without a stoppage but had no parts breakages. I dry fire almost daily and the guns are usually bone dry at the end of the challenge, which is a problem for Beretta's as they like to run wet. I have started using grease (Lucas Red "n" Tacky #2) on my DAO centurion and I'm quite pleased with it, there is still lots of lube where it's needed after 1752 rounds.
I do replace the trigger return springs and recoil springs after several thousand rounds, but I've never had one break. The mags require more frequent cleaning and I usually only get a couple range sessions before they should be cleaned or I risk having the followers bind. But the mags get dumped in gravel, dirt and puddles so you can't really blame the mags. Also, the extractor should be cleaned every 4k rounds or so.
Other than that they are reliable guns. I run standard weight recoil springs and keep em cleaned/lubed and never really have a problem.
