Starting with Timney’s Alpha Competition trigger platform, the Ultimate Builder’s Kit for GLOCK Gen 3/4 also includes a striker, striker spring, connector, safety plunger, and safety plunger spring. The striker, made from stainless steel, matches the geometry of the Alpha Competition sear, while the safety plunger matches the geometry of the Alpha Competition trigger bar and is made from tool steel. All Ultimate Builder’s Kit parts are heat treated and NP3 coated for durability and increased lubricity. With a factory set pull weight of 2.5 to 3 pounds, the Timney Alpha Competition UBK trigger kit answers the call for a trigger that maintains the feel of a Timney Trigger all while upholding the dependability of the GLOCK system. This model features an internal pivoting safety shoe instead of the traditional safety-blade on the trigger face. Fits: Medium frame, double stack GLOCK Gen3 Gen4 pistols (not compatible with single stack or large frame handguns i.e. 10mm or .45ACP) Please note: this trigger is only compatible with stock GLOCK pistols and intended for competition use only.
