From 1-May-09 to 19-Mar-10 — 322 days — the pistol fired 91,322 rounds.
Of those 322, it spent 130 days at the range, averaging over 700 rounds per trip.
It spent 512 hours at the range, averaging almost 180 rounds per hour. By the way, 512 hours is more than three weeks at twenty four hours per day, seven days a week.
That rnd/hr number is a bit skewed, though, because it includes many hours on the range teaching. When you look at just my personal practice routines, the gun was regularly firing 350-550 rounds per hour.
During the entire test, the pistol experienced a total of thirteen stoppages. Those who have followed the test from the beginning will remember that the first seven were the result of an out-of-spec mainspring that was replaced before the 10,000 round mark. The last three, as reported above, were in quick succession due to the gun reaching the end of its service life. Between the time when the mainspring was replaced and the gun’s final death throes, there were only three stoppages… that’s less than one stoppage per 27,000 rounds fired.
So what finally brought the gun to a stop? Heat. As Sam explained it, the part of the frame that was damaged is in contact with the recoil spring assembly. Every time the gun is fired, heat gets transferred through the barrel lug to the recoil assembly. Under any normal condition, that is not a problem.
But while many folks have criticized the term “torture test” to describe the pistol-training.com endurance tests, torture is exactly what these guns are subjected to. In 91,322 rounds, the gun was only cleaned fifteen times — once going over 12,000 rounds between cleanings. It was rarely lubed more often than once every 4-5,000 rounds. Multiple days per week it was subjected to consecutive hours of high volume rapid fire practice that often made the gun too hot to touch.
