I have a SIRT pistol and picked up a LaserLyte Score Tyme from Amazon to try out. It arrived today and I gave it a brief try at 10yd indoor while my wife was out shopping. It works pretty well with the SIRT pistol but one has to cycle the trigger quickly to avoid “drawing” on the 7” target, as the SIRT laser stays on if the trigger remains pulled back.
It’s stupid expensive but very quick and simple to use, versus setting up some other systems. As I shoot guns that require a slide rack to reset (Glock 19 and SIG P365) using the SIRT is a compromise but I figure I’ll use it more often. I have a month to return it for a full refund so will use it frequently to see if it’s worth keeping.
