This product is an excellent way to train without the cost of live ammunition for those who want to use their devices. Easy to install, the cartridge emits a laser when the trigger is depressed, letting you know exactly where your shot would have gone.

This product will not change the function of your device - if yours is striker-fired, you will need to re-rack the slide after each shot. The cartridge is rimless, meaning the extractor will not catch the cartridge or eject it. Uses 3 LR626 batteries, providing an exceptionally long battery life.
