The Align Tactical® THUMB REST LOCKING BLOCK PIN is compatible with Canik® Rival/Mete/TTI® series "polymer" pistols with the [ SQUARE RECESS ] feature in frame ONLY. (NOT COMPATIBLE with TP9 Series, TP9 SUB METE, Mete MC9 Micro, or most **RIVAL-S steel frames). Hardened S7 tool steel part finished in Black Nitride. Approved for USPSA Limited Optics, Limited, Limited 10, and Open divisions. Made in USA with lifetime warranty.
*Holster selection requires clearance for extended ledge. Refer to Align Tactical's Compatible Holster Manufacturers for select models.
**NOTE: RIVAL-S steel frame forgings vary widely in feature dimensions/tolerances and may either be drop-in or require significant fitting of the anti-rotation stop by a gunsmith (up to 1mm of machining or diamond filing of square anti-rotation stop's inside and top edge) GUNSMITH NOTE - Rival-S installs must be a HAND-PRESS ONLY insertion. Any hammering torque applied to the L-shaped pin will induce part stress (to the 3mm pin base) and not yield to the thick frame forging (resulting in prying force and breakage upon driving-in or after repeated recoil). *Legacy TP9 Series are not an option due to design limitations (no square recess and uses roll pins). -- New TTI Combat (Taran Tactical Innovations) frames vary between a perfect fit or hair of play. Can be shimmed rock-solid with a sliver/shaving of material placed between a side wall of the frame recess and the anti-rotation stop upon insertion.
