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.
