Timney Triggers Alpha Competition Trigger Fits GLOCK Gen 3 4 in 10MM or 45ACP 20 21 30 29 Black Alpha Glock 3 4 LARGE BLACKOUT UPC 081950753888
Product Description
The Timney Triggers Alpha Competition Series Trigger for GLOCK Gen 3 and Gen 4 Large Frame models in Blackout (MPN: ALPHA GLOCK 3-4-LARGE-BLACKOUT) is an engineering breakthrough designed to transform the trigger pull of 10mm and .45 ACP GLOCK handguns. Purpose-built for competitive action shooting and precision target work, this drop-in trigger mechanism converts the traditional factory GLOCK trigger feel into a ultra-crisp, light 3.0 lb break with a rapid, tactile reset.
Re-engineering the internal firing geometry, the Alpha Competition Series utilizes a proprietary receiver block and sear design that maintains full striker engagement while fundamentally altering how force is applied. Featuring a Teflon Nickel (NP3) treated trigger bar and sear, the system virtually eliminates friction and creep, offering an unbelievably smooth pull without compromising standard GLOCK drop safety integrity.
The straight aluminum shoe features a flat face with a subtle bottom sweep and an integrated safety blade, promoting consistent finger placement and flat-rearward trigger press vectors. Precision-manufactured in the USA, the ALPHA GLOCK 3-4-LARGE-BLACKOUT drops directly into GLOCK Gen 3/4 20, 21, 29, and 30 frames using factory receiver pins, delivering match-grade trigger performance to large-frame GLOCK shooters.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits large-frame GLOCK Gen 3 and Gen 4 models chambered in 10mm Auto and .45 ACP (GLOCK 20, 21, 29, 30, 40, and 41). (Note: Will NOT fit small-frame 9mm/.40 S&W/.357 SIG GLOCK models, nor Gen 5 frames or Slimline 42/43/43X/48 pistols).
- Perform a complete firearm safety check: drop the magazine, pull the slide rearward, lock it open, and visually/physically inspect the chamber to verify zero live rounds are present.
- Field strip the firearm and push out the housing pin, trigger pin, and locking block pin to remove the factory trigger bar and mechanism housing.
- Install the Timney receiver block component into the bottom channel of the trigger housing socket.
- Drop the assembled Timney Alpha trigger bar and shoe mechanism into the frame, aligning the mounting holes with the frame locking block.
- Reinsert the locking block pin, trigger pin, and rear housing pin, ensuring proper seating of the slide stop lever spring under the top pin.
- Perform a manual function check using an armorer's inspection plate to verify crisp 3.0 lb break, positive reset, and 100% striker safety engagement before live firing.
