Check the listing for details. Align Tactical Thumb Rest Paddle Trigger Pin for Glock Gen1-4 19/23/25/26 & More. Color: Black, Condition: New. Listed at 61.95 USD. 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. Compatibility:Gen 1-4 Glock 19,23,25,26,27,28,29,30,32,33,38,39*Holster selection requires clearance for extended ledge.
