Product Overview and Introduction

Conquer fast-paced competition stages and rapid-fire strings with the Geissele Automatics Super Dynamic 3 Gun (SD-3G) Trigger featuring a match-grade Flat Bow and a lightning-fast Single-Stage Hybrid Design – MPN: 05-166. Engineered specifically for 3-gun shooters and dynamic tactical competitors who demand split-second speed, the SD-3G delivers an ultra-smooth, lightweight pull with a hybrid-break characteristic that bridges the gap between single-stage speed and two-stage control.

Whether you are sprinting through a 3-gun bay, shooting tactical matches, or building a high-performance competition carbine, the SD-3G provides the rapid lock-time and crisp reset required to stay ahead of the clock.

Lightning-Fast Hybrid Single-Stage Performance

Engineered to exacting tolerances, the SD-3G combines innovative internal geometry with a flat match bow to maximize your shooting speed:

• Hybrid Single-Stage Pull: Features a smooth, rolling take-up that breaks cleanly at approximately 3.25 pounds. Its unique design offers the speed of a traditional single-stage trigger with the safety margin of a rolling break.

• Flat Match Bow Design: The flat trigger face provides a consistent finger placement surface, allowing for a straight-back pull and enhanced leverage for rapid, repeatable trigger manipulation.

• Short, Lightning-Fast Reset: Designed with an exceptionally short and tactile reset, enabling rapid follow-up shots and lightning-fast split times during high-speed drills.

• Full-Power Hammer: Utilizes a robust, full-weight hammer to ensure 100% reliable ignition across all commercial and match ammunition types without light strikes.
