B&T USW ENHANCED TRIGGER KIT

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.

  **DO NOT DRY FIRE WITHOUT SNAP CAP**

Extended firing pin (properly hardened)

    Trigger kit for USW

    Posted by B&T Enhanced USW Indeed on Jan 26th 2018

    Well done- found the video on youtube and ordered the kit for my USW A1. Followed along in the video and all is installed. 1-2-3 easy. I also found you can use a pocket knife instead of a dental pick if needed to lift the spring out... when you get to that part you will know what I mean. Good Stuff cant wait to see how my groups turn out.

    Can't believe the difference this kit made. dropped the trigger pull by almost 5 lbs and all ammo I have tried goes off without any issue. No one else has made anything for this gun this is the only thing it needs. Ben
