Glock Gen 5 Large Frame – Alpha Competition Trigger – 3 lb Break – Fits G20/21/29/30/40/41


PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

The Timney Triggers Alpha Competition Trigger for Glock Gen 5 large frame pistols is built for shooters who want a lighter, cleaner break without turning their pistol into a mystery box. This trigger family is verified for Glock 20, 21, 29, 30, 40, and 41 Gen 5 models and carries a factory-rated 3 lb pull weight.

Available options are organized below under Variants.

Verified color options in this group are Bronze, Gold, Green, Orange, Purple, Red, and Silver. Timney’s published specs for the Gen 5 large frame Alpha line confirm a Teflon nickel-coated sear and trigger bar, use of stock Glock parts and springs, and competition-focused design intent.

What it does

This trigger replaces the factory trigger setup with Timney’s Alpha Competition design to deliver a lighter pull, cleaner break, and more refined feel for competition-oriented shooting. The published 3 lb pull weight and low-friction coated sear and trigger bar are the big story here.


Why it’s worth it

If a customer wants a real trigger upgrade for a Gen 5 large-frame Glock, this one makes sense. Timney has name recognition, the specs are clear, the fitment family is specific, and the color options let the buyer add a little personality without getting lost in gimmick land.

Tools needed

A proper Glock armorer’s punch and basic bench setup are typically all that is needed for installation, but that does not mean the job should be done sloppy.


Install notes

Timney states the trigger can be installed without a gunsmith, but trigger work is still function-critical work. Safe installation, post-install checks, and proper live-fire validation matter. This is not the place for “good enough.”


Verify before you buy

Verify to prevent returns: make sure the pistol is a Glock Gen 5 large-frame model, specifically G20/21/29/30/40/41, and choose the correct color: Bronze, Gold, Green, Orange, Purple, Red, or Silver.
