The Geissele Super 3 Gun (S3G) trigger is a semi-automatic-only derivative of the two-stage Super Select-Fire (SSF) combat trigger that Geissele Automatics produces for customers in the U.S. Special Operations Community. The S3G was developed to combine the SSF combat trigger’s match-grade semi-automatic performance with its smooth single-stage full-automatic feel to make a fast, smooth, and robust trigger ideal for 3 Gun competition shooting. Note: 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.
