Sig Sauer fans wanted something compact and lightweight that performed like a full size. Enter the P238 in. 380 and the P938 in 9mm. To enhance targeting acquisition of this fine shooting compact, Crimson Trace’s LG-492 Laserguard attaches to the trigger guard of the P238/P938 by two factory supplied screws. The LG-492 is fully adjustable for windage and elevation and comes sighted in at 50 feet from the factory. BRIGHTNESS: Features a 5mW peak, 620-670nm, Class 3R visible red laser that is in conformance with and complies with 21 CFR 1040.10 with a max power output of 5mW for a Class 3R Red Laser – the brightest beam allowed by law. RUNTIME: 4 hours of battery life that runs on (1) 1/3N battery (included). EASE OF USE: Front activation button engages the laser immediately when the firearm is held in a normal firing grip – this model features a master ON/OFF switch for completely powering down the unit – user installed – no gunsmithing required. RELIABLE: Factory sighted at 50 feet, but is fully user adjustable for Windage and Elevation with provided tool. FITS: Sig Sauer P238 / P938 (does not fit P938 BRG, P238 DESERT, P938 22LR TB).
