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 SD-3G 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 SD-3G s flat trigger bow 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 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. It is designed for close course competition use where rapid target engagement with quick follow up shots are required.
