Just finished the "SIRTification Course" with Mike Hughes. Spent a day learning the system, seeing techniques and methods, then the 'armorers' portion where we learned to change batteries and adjust the trigger.
Well worth the time and effort. I can see this as a great tool to work on sight alignment and trigger press. I've bought several for my basic class. Mike worked with Rob Pincus/Personal Defense Network on a DVD titled, "Extreme Shooting Skill Development" which does a great job of showing many applications of the SIRT pistol. Topics covered: Shooting Mechanics: Grip, Shooting Mechanics: Trigger Control, Classic Shooting Fundamenals, ive Fire Practice: Random Drill, Laser training Integration: Sight Alignment/Sight Picture, Laser Trainer Integration: Trigger Control, Off-Range Dry Fire Training Session, Dry Fire Presentation from Your holster & reloads, and NLT Rapid Shot Drill.
