Included in your purchase is the Ambidextrous Tactical Laser Holster that fits the TR41-G Green ArmaLaser, plus the TR41g Green Laser and 2 extra batteries for a total of 3 batteries. Holster has extra magazine pouch and is adjustable (optional pocket, IWB or belly-band holster available to subst.). LASER FIT: Touch-Reflex TR41-G fits the Taurus GX4, GX4 XL and GX4 XL TORO (does NOT fit the GX4 Carry with a rail) Featuring a 5-year warranty, the TR41-G 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 TR41-G features a convenient battery door to replace its single CR1/3N battery (also can use 2 357 watch cells) 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. Arma Lasers are Class IIIa with a peak power output less than 5mW and are registered with the FDA as a laser manufacturer. There is a very big difference in laser brightness between a 650nm laser and the 635nm one used in the TR41-G, especially during daylight. It's incredibly strong and sturdy with incredible abuse-absorbing rigidity. Requires no tools, pin removal, or gunsmithing. Installs easily in minutes and is simple to adjust to point of aim. Best of all, it stays adjusted no matter how many rounds you fire. The TR41-G can also switch between a steady laser beam mode and pulsing beam mode. (*Please note: only the laser sight, holster and batteries are being sold - NOT the gun.)
