Timney UBK for Glock Gen 3-4

The Ultimate Builder's Kit by Timney Triggers delivers a lighter, smoother trigger pull in Gen 3 - 4 GLOCKs without sacrificing any reliability. It includes Timney's Alpha Competition Trigger platform with a set pull weight of 2.5 to 3 pounds, as well as 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.
