The Timney Alpha Competition Trigger for Glock Gen 3/4 10mm/45ACP 20/21/29/30, Black is a trigger that fits GLOCK Gen 3/4 in 10MM or 45ACP (20/21/30/29).
With a factory pull weight of 3 pounds, the Timney Alpha Competition trigger answers the long call for a trigger that has the same feel and performance that matches the reliability of the Glock system by providing an improved trigger design that does not sacrifice any part of the Glock reliability.
A replacement trigger changes the pull weight, travel and reset, which is one of the most effective ways to improve accuracy. Trigger work affects safety: have it fitted by a competent person or gunsmith, follow the manufacturer's instructions, and function-check the rifle before live fire.
