The LG-437 laser sight for Kahr Arms 9mm and .40 pistols provides an instinctive front-activation point that engages with your natural firing grip. Simply hold the weapon normally and the Laserguard activates, placing a bright red dot where the gun is aimed. Seamlessly mounted to the trigger guard, this instinctive solution is critical to personal defense, and an excellent way to outfit your premium quality Kahr Arms concealed carry weapon. Based on machining variances between pistol models, it is possible that some consumers may experience a slight gap between barrel and Laserguard. This does not affect overall fit and function of the laser sight in any way, shape or form.
