I shoot a SIG 320 topped with a Delta Point Pro in 9mm. There is no stipulation for equipment other than striker fired with red dot optic. There were only three manufacturers represented at the class. Keep in mind these are all duty rated pistols not what I would call “enthusiasts “ pistols. SIG, Glock and one SnW the Smith pistol broke down on day two. Keep in mind this is basically just over 1,000 rounds in a compressed time, at a very high rate of fire, in essence maintaining 1/2 second splits for the two days. In and out of holster a million times. It is brutal on equipment. Magazines dumped in mud and rock, brushed off or sprayed with water bottle and put right back in the pistol to go again. This kind of training most folks never experience or can imagine. It is very hard on your body mind and equipment. I was exhausted mentally and physically. Imagine if you will explaining to a guy that races his car once or twice a year from stoplight to stoplight on the street the brutality of a three day weekend high dollar payout race weekend. It is like that!
