Glock Gen 5 – Ultimate Builder’s Kit – 2.5–3 lb Pull – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Timney’s Ultimate Builder’s Kit for Glock Gen 5 is a matched trigger-system upgrade built around the Alpha Competition trigger platform. This black kit is made for stock Gen 5 medium-frame, double-stack Glock pistols and adds more than just the trigger itself by pairing the system with a striker, striker spring, connector, and safety plunger engineered to work together.
This is the more complete route for shooters who do not want to piece together a trigger setup one part at a time and then act surprised when geometry stacks weird. Timney lists the kit at a 2.5 to 3 lb pull weight, with NP3-coated parts for a smoother press and better consistency.

What it does
This kit upgrades the Glock Gen 5 fire-control system with matched parts designed to improve pull feel, reduce friction, and maintain proper geometry across the trigger assembly. Instead of only swapping the shoe and calling it a day, the UBK adds the supporting pieces that help the system work together as a complete setup.
Why it’s worth it
If someone already knows they want more than a basic trigger swap, this is the cleaner path. The matched striker, connector, and coated parts make more sense than cobbling together random parts from three brands and hoping the gun appreciates your creativity.

Install notes
This is a function-critical fire-control kit, not a cosmetic bolt-on. Install it correctly, verify safe operation, and perform full function testing before live fire. Competition parts are not where you wing it and trust destiny.
Verify before you buy
Verify your pistol is a stock Glock Gen 5 medium-frame double-stack model and not a large-frame version. Verify you want the black non-adjustable Ultimate Builder’s Kit before ordering.
