FIRE SELECTOR SYSTEM for Glock Pistols is a state of the art product developed by the
firearms inventor Jorge A. Leon in 1987.
The FSSG consists in a system for selectively converting an existing Glock pistol between
semi-automatic and full-automatic operation.
FSSG is quickly attached on any Glock model without altering the gun.
The FSSG is protected under U.S. Patent # 5.705.763 and foreign international patents
