The Geissele Super 3 Gun (S3G) is a semi-automatic, hybrid cross between a single-stage trigger and a traditional 2-stage trigger. Its robust feel and light pull weight, combined with a lightning-quick reset, make this trigger ideal for any 3 Gun competitor. The S3G 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.
