Official Product of Ultimate Arms Gear, Brand New. How it works; Black Upper: This device reliably increases first shot trigger pull by ~6 lb + 5.5 lb factory trigger, it increases to ~11.5 lb. Yellow or Pink Upper: This device reliably increases first shot trigger pull by ~17 lb + 5.5 lb factory trigger, it increases to ~22.5 lb and can be accurately shot through. The Trigger pull automatically decreases to factory weight after the first shot. Trigger action is similar to, but better than, DA/SA pistols. SAFE-DRAW Passive Safety makes reaching for a gun safer and helps prevent accidents, especially in high-stress situations. Clips on to the trigger guard without tools and is usable until the shear pins have been broken. The shear tab locks in place after the first shot. Installation: Ensure gun is unloaded and pointed in a safe direction at all times before and during installation. Follow the animation above. Check to make sure that both sides click shut. The Passive Safety mounts firmly when pushed rearward towards the grip. It will not fall off the gun during rapid fire or while carrying.
