The Geissele SD-3G solves the problem of slow target transitions in competition shooting where every millisecond counts. It excels at closed-course 3-gun competition where rapid target engagement with quick follow-up shots is critical. The hybrid trigger pull gives you the speed advantage of a single-stage with the controlled break of a two-stage, while the flat bow design enhances tactile feedback and reduces perceived trigger weight. What sets the SD-3G apart in the competition trigger category is this unique combination of shortened pull length, lightning-quick reset, and the safety features of a two-stage combat trigger design—built specifically for speed without sacrificing control. Note: This trigger is designed specifically for closed-course competition shooting and is not recommended for duty use, bench rest shooting, or precision accuracy work.
