LaserLyte's Trigger Guard Mounted laser for Taurus 738 TCP and 709/740 Slim pistols features the LaserLyte Master Module system. The versatile Master Module fits into the gun's housing seamlessly, matching the gun's dust cover and trigger guard with perfect fit. Each TGL package comes with two housings per model and will fit two guns for the price of just one laser. Simply remove the single screw to swap out laser housings. A laser swap can easily be made in under a minute. It has two modes (pulse or constant on) activated by ambidextrous on/off switch, and an auto-off feature to turn the laser off in six minutes if it is accidentally activated. Initial installation onto the gun will take less than five minutes and the laser does not require removal in order to change out batteries.
