Whoops, I left this out of my previous SHOT 2014 wrap-up on accident! The folks from Next Level Training were showing-off their SIRT (Shot Indicating Resetting Trigger) pistol shaped like Smith & Wesson's M&P. I've been attracted to the SIRT pistol for several reasons, but since I'm an M&P shooter I haven't wanted to buy one because it's shaped like a Glock.
First, they're the perfect dry practice pistol since they can't fire any ammo, making them much safer to practice with in a typical residential environment. Second, the trigger resets automatically. This means I don't have to run the slide after each dry press, which interrupts my practice if I'm making consecutive presses and ingrains a bad habit of racking the pistol after each shot. Third—and the main reason for the SIRT pistol—the lasers indicate when the trigger is prepped and then where the shot would have landed when the sear breaks. The larger the distance between these two points, the less control you're exhibiting over the trigger.
Even after all my years of shooting pistols, I still find I greatly benefit from practicing my trigger fundamentals. While I do practice dry, I don't do it as often as I should partly because the M&P trigger doesn't reset unless I run the slide, which in my mind limits me to single press practice. While Next Level Training still hasn't updated their website with any information about the M&P version, I hope they get them out the door soon. I want one!
