Geissele Automatics SD3G Super Dynamic 3 Gun Trigger
Built for Speed. Engineered to Win.
The Geissele Automatics Super Dynamic 3 Gun (SD3G) is purpose-built for shooters who demand maximum speed and rapid follow-up shots. Featuring a flat trigger bow and Geissele's unique Hybrid Rolling Break, the SD3G combines the best characteristics of a single-stage and two-stage trigger into one exceptionally fast, competition-ready package.
The SD3G features an extremely short pull, lightning-fast reset, and reduced perceived pull weight thanks to its flat-faced design. Whether you're running a 3-Gun stage, USPSA rifle match, or any fast-paced competition, the SD3G helps shave valuable time between shots while maintaining the durability and reliability Geissele is known for.
Note: The SD3G is designed specifically for competition use and is not recommended for duty rifles, precision shooting, or benchrest applications due to its exceptionally light pull and rapid reset.
