i put 2,000 round in mine with in 30 days i also installed a m&p night site with a hammer and a drill bit also i beat the hell out of this pistol and polished it....costly project of mine anyways with the beat down and used it like its stolen it still works 3,900 rounds
i think it lasted better then the glock but thats how i see it...apex springs and trigger/recoil spring and stainless guidrod with steal sites and w.e upgradesyou can find you will love that pistol forever
