Fire 10,000 rounds with NO malfunctions (No FTE, No FTF, Nothing)...
You cannot clean the gun, you cannot replace components that you think may be getting worn.
As for pistols, I've personally had one that did just that ... went 10K rounds without a malfunction of any kind. I did clean it three or four times in that period; no parts replacements during that time, including springs. It just kept on trucking. A Browning BDM. Had it new since 1994. Shot about 28K rounds then something went "click" in the gun's character. It simply decided to throw in the towel, so to speak, in terms of the occasional problem. It fed everything. It ran smoothly. It was
very accurate inside ~50ft or so, to the degree I could begin to carve out little circles in the target paper as far as 10yds, to handspan-diameter groupings of 15rds at ~50ft when fired briskly. "Kept," I said, because (believe it or not) I sold it to acquire another gun. Sometimes, there just aren't words for how silly are the things we do. :embarassed:
My CZ P01 is doing very well. Hasn't quite broken in. By 10K rds, it should be to the point where I could expect it to run the next 10K rounds without a hitch of any sort. It started out nearly perfect and is getting better all the time, in terms of smoothness, ability to eat any sort of ammo, etc. I've gone long periods without cleaning, during stress tests. It, likewise, just keeps on going.
Had a friend with a well-used HK USP that he swore was error-free. At the time I knew of it, he'd had perhaps 5K rounds through it. He occasionally cleaned it.
I've heard stories, from time to time, of the occasional 1911 that runs that long without problems, though I'm certain those are cleaned regularly.
But, to wager $1000 on a given gun doing that, without cleaning? That broken-in Browning BDM 9mm pistol is the only one I'd consider, and that's because I'd seen it do that once before. Otherwise, I'd think it's a good way to lose $1000.
