Included in your purchase is the Tactical Laser Holster that fits the TR30 ArmaLaser, plus the TR30 Laser and 2 extra batteries for a total of 3 batteries. The holster also fit an extra magazine and is ambidextrous and adjustable. LASER FIT: Touch-Reflex TR30 fits Kel-Tec PMR30. Featuring a 5-year warranty, the laser sight turns on by human touch, not by a mechanical switch or button. As soon as you grasp your pistol, the True-Touch Activation sensor will turn the laser on and keep it on as long as you're grasping the pistol grip. Move your middle finger forward and the laser will shut off. It is seamless, immediate and requires no button to be pushed or secondary operation. The laser features a convenient battery door to replace its single CR1/3N battery so you won't lose any of the laser's ''zero'' when replacing batteries like with other lasers. A master kill switch is recessed into the DuPont Zytel fiber-reinforced nylon housing (same material used on some gun frames) to allow practice without the laser if needed. Incredible 5 hours of run time and up to 2 years of standby time even if the laser is placed in ''ready to activate'' mode. FDA Class IIIa Laser Product (Does not exceed Class IIIa emission limits), less than 5mW power output.
