10,132 to be precise. Got the gun in January. I remain impressed! The gun has eaten a bunch of aluminum case, 2000ish rounds of steel case, and of course brass. I have had some malfunctions, but I attribute these to knock off magazines. Only my one 33rd Glock mag and 17rd Magpul never bobbled on steel case for instance. 3 ETS mags and a SGM haven't been quite as good. Still, well below 1% failure rate. Due to cost I've shot only half a box of HST +P, no issue. Few boxes 147g flat points AL case no issue. I sent the gun back to Extar around 6000rd for loose barrel. They admitted some guns went out around my time improperly torqued. Turn around was 9 days. Bottom rail screws have been a little problematic coming loose. The only wear I can identify is some plastic slight lengthening of the ejection port. Even today, specifying real Glock mags, I would load up defensive ammo and trust this gun completely.
ETA This is a minimum round count. I shoot in my back yard and it's probable that I forgot to record every time I shot.
