The 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 pending.
