Geissele Automatics Super Dynamic 3-Gun Trigger
The Geissele Super Dynamic 3 Gun (SD-3G™) trigger is the flat trigger bow version of the Geissele Super 3 Gun (S3G) trigger. Like the S3G, the sd3g trigger has a shortened pull length and a lightning-quick reset to give it a unique, hybrid trigger pull that is a cross between a traditional two-stage and single-stage trigger while still retaining the safety and robustness of a two-stage combat trigger. The flat trigger bow of the Geissele Automatics Super Dynamic 3-gun trigger further enhances the trigger’s performance by reducing the perceived pull weight and improving the trigger’s tactile feedback to the operator, making it ideally suited for 3-Gun competition shooting.
The Geissele SD3G trigger has a very short, light pull and reset. We do not recommend it for duty use, bench rest, accuracy work, or shooting small groups. The Geissele SD3G trigger is designed for close-course competition use where rapid target engagement with quick follow-up shots is required.
