The Stanislawski SoleX is a single sear design with a rock solid trigger with adjustable travel. The travel on the SoleX can be adjusted to the point where there is zero perceived trigger travel. The SoleX uses a patent pending self-locking travel adjustment pin, this pin allows for twice as much precision then a 8/32 set screw for a truly micro-adjustable trigger. The trigger and hook are made from a custom formulated 440C stainless steel with Dimond Like Coating for increased strength, friction reduction, and corrosion resistance. The open hook, trigger system, and spring loaded return make the SoleX a great choice for hunters looking for a rock solid index finger activated release.
