Align Tactical Glock Gen 3-4 Compact Thumb Rest Trigger Pin

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.

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.

Glock Trigger Pins incorporate grooves that are retained by the slide stop under spring tension. Two shallow grooves are engaged by GEN 5 ambidextrous slide stops vs. a single deep groove for legacy generations that utilize a (second) dedicated locking block pin to dissipate force.

For easier pin removal, lift the slide stop to help center it to the pin grooves. Push the Trigger Pin out with a punch or use the Thumb Rest Trigger Pin itself to swap. NOTE: Initial removal may require a bit of pressure.

For pistol disassembly, partially back out the Thumb Rest Trigger Pin, allowing the anti-rotation stop to clear the frame's slide lock channel and then rotate it clear. Re-install on a fully assembled pistol (AFTER slide is attached), to lock in place.

We've enhanced the line to reflect the following dedicated products. There are two features that determine compatibility, with the first being the aforementioned Trigger Pin Groove (DEPTH), and the second being the (DISTANCE) between the trigger pin to the slide lock disassembly channel.

Legacy GEN 1-4 COMPACT models & Current GEN 5 (including all models that utilize an ambidextrous slide stop) share the "SHORT" distance, while differing in groove depth.
