LaserLyte Firing Pin Activated Pistol Laser Trainer Cartridge for .40 S&W Auto Caliber.

The LaserLyte .40 S&W Laser Trainer Cartridge that offers a revolutionary way to train almost anywhere. The .40 cal Laser Trainer Cartridge fits inside the pistol chamber and features a firing-pin activated switch that indicates bullet impact with a bright red laser dot.

The .40 S&W Laser Trainer Cartridge easily installs into the firing chamber in seconds, works regardless of barrel length and does not stick out of the barrel. It activates for 100 milliseconds each time the firing pin strikes the cartridge. This modified cartridge is rimless, so the Laser Trainer Cartridge is not expelled during dry fire, which allows for tap, rack, bang or malfunction training drills.

A hardened rubber plunger on the laser also acts as a built-in snap cap to protect the firing pin and two rubber rings on the laser help ensure a proper fit in order to best replicate bullet impact for accurate training. The Laser Trainer Cartridge requires three 377 batteries, good for approximately 3,000 shots.
