We finally took action and created a kit that not only makes the B&T USW a better combat pistol but now a contender for competition shooting. Our kit not only redesigns the the springs inside the USW but also the firing pin to allow for a extreme reduction of the hammer spring by over half the original weight, without compromising safety of the pistol. We have also redesigned the way the hammer spring compresses and Incorporated a unique staging of the trigger to reduce trigger weight during the start of the pull, insuring you do not jerk the sight picture in double action. We recommend you test your ammo with all springs starting with the yellow spring, testing has shown the 8lb spring can have a fail to fire with the very hardest primers at times. Trigger pull at an incredible 3lb 11oz in SA and 7lb 5oz in DA possible with this kit on a stock gun, finally making it competition ready for fast accurate shots on target.
