The SoleX is a single sear design that gives a remarkably solid trigger that can easily be set to have zero percieved trigger travel. The SoleX has the patent pending self-locking travel adjustment pin that is 2 times as precise as a standard 8/32″ set screw for a truly micro adjustable trigger. The trigger and hook are made from custom formulated and enhanced 440C Stainless Steel and Dimond Like Coated (DLC) for increased strength, friction reduction and corrosion resistance.
