9mm Laser Training Bullet,Laser Bullet, Laser Cartridge for Dry Fire Training and Shooting Simulation we designed the laser bullet for training and shooting simulation. This is laser trainer cartridge not laser bore sight. It can help you shooting more accurately. Also no t fit SigSauer P250/320!! The back cover can work 300-500 times, then you need to buy a new back cover to replace The laser will turn on for about 0.5seconds when the trigger is pulled and will turn off automatically. The laser will turn off even if the firing-pin is pressing of the end cap of the bullet. 1. 9mm Red Dot Laser Training Bullet Introduction: The caliber 9mm bullet is a red laser Bore Sight for training and shooting simulation.
