After several requests for a better trigger in the Sphinx SDP Compact pistols from customers. We finally took action and created a kit that not only makes the Sphinx SDP Compact a better combat pistol but now a contender for competition shooting. Unlike other kits on the market which have poorly made springs that do not retain safe operation of the firing pin during a drop incident. Our kit not only redesigns the the springs inside the Sphinx 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 4lb 10oz in SA and 7lb 13oz in DA possible with our kit, finally making it competition ready for fast accurate shots on target.

 

**Beware of other companies who are trying to knock off our kit for a little less money and sell you a product that is not made to the same standards as our the original "Sphinx Enhanced Trigger Kit™" or "B&T ENHANCED TRIGGER KIT™" high quality standards. Our products are made to the same Sphinx standards and made in the USA - not China, Just because they look similar and use our product name - it is not the same ...at ALL.**

    Happy with the reduced pull weight. The gun is much smoother in DA. Definitely worth the money. Would purchase again.

    Perfecta ammo

    Posted by Steve Reeder on Aug 6th 2018

    Trigger kit definitely helps with pull weights. Tried all sorts of combinations with springs but even with the heaviest main spring and lightest fp spring, I still got a single light strike in about 75 rounds using Perfecta 115grain. Will try different ammo and overall I like the kit since I only use this gun for plinking.
