I've shot about seven-hundred rounds of the ammo by my Glock 19 and it's verified for being 100% reliable. Zero FTE's or FTF's. It is quite precise and an incredible worth. My only complaint is that it's somewhat dirtier than some ammo, but undoubtedly not sufficient of a difficulty to halt employing it.Superb ammo. My cz 457 enjoys these items. Id
