These manufacturers have tested and validated compatibility with Align Tactical performance components for select holsters in their existing product line.

Holster selection requires clearance for extended ledge. Refer to Align Tactical's Compatible Holster Manufacturers for select models from Black Scorpion Gear, Werkz, Safariland, Red Hill Tactical, Priority 1 Holsters, GX Products, Red River Tactical, Black-Rhino Concealment, and Lytton Custom Holsters.


Master Recoil

The Align Tactical® THUMB REST TRIGGER PIN integrates an ergonomic ledge for the support hand's thumb to firmly lock down against, serving as a brake against muzzle flip to provide the fastest follow-up sight picture. Increased surface contact with the pistol reduces support hand slippage while providing an index point for a consistent high thumbs-forward grip. Swaps in seconds to offer maximum control and speed in Glock® and select Glock-compatible pistols for a competitive edge.

Secure Design

The Thumb Rest Trigger Pin utilizes a patent-pending forked design that leverages the disassembly channel's (opening) as an insertion point for accepting an anti-rotation stop. Pushing the trigger pin partially out (of an UNLOADED PISTOL), allows the anti-rotation stop to clear the disassembly channel so the slide lock can be pulled down for normal disassembly.


There are two distinct distances between GLOCK's OEM Trigger Pin and the slide lock. These vary between the older (INCOMPATIBLE) "long" Gen 1-4 Competition/Standard models (pictured in red below) and the "short" Gen 1-5 (COMPATIBLE) Compact/Sub-Compacts (in green). All Gen 5 models universally switched to the same "shortened" distance for expanded compatibility (Excludes Slimline models).

Glock platform pistols that maintain this specification are also compatible, such as Shadow Systems, SCT, Nomad Defense, PSA (Palmetto State Armory) Dagger, Stoeger STR-9 series (excluding MC), Glockstore GSX100, ZRODelta ONE and more... (Shadow Systems MR series are a normal fit, while XR and DR series are a "hair" farther apart creating a tighter press-fit). Polymer80 not compatible.

Every compensator we manufacture has undergone rigorous reliability testing!

The design phase

Every product we make goes through a week long design process and multiple versions before we machine a prototype!

CNC Machining

We currently machine all of our compensators on 2 brand new Doosan DNM4500S CNC milling machines and a 2019 Tormach 1000mx CNC milling machine!


The answer is easy! All you need to do is purchase the threaded barrel that matches your slide. For example, if you have a carry length slide you need a carry length threaded barrel (4.6"). If you have an X compact slide you need a X compact threaded barrel (4.3"). This will allow you to run a longer frame and give you an integrated look.


Yes they do. We have run tens of thousand of rounds through all of our models and have had zero malfunctions. If you are having an issue with a build, it is likely the case you have installed our prodcut incoretly or your handgun needs broken in. Compensators need a smooth running system to be reliable. A new handgun has tolerances that need to be worn in before we suggest adding a compensator

-It's easy! We designed our comps to be self-timing so all you have to do is

- Remove your slide from you frame

- Remove your guide rod assembly

- Apply Loctite to barrel threads

- Thread comp onto barrel until it stops

- Back off a 1/8 turn

- Apply Loctite to set screws

- Tighten down set screws
