Align P320 Thumb Rest Takedown Lever
|
The Align Tactical® THUMB REST TAKEDOWN LEVER 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 Sig Sauer® P320® (M17/M18)® pistols for a competitive edge. Establishing a two-handed grip creates a naturally angled cant of one’s support hand thumb. Incorporating a secondary receiving slope of 15 degrees allows for evenly distributed thumb pressure and serves as a guide for settling into proper contact position (with the center of the thumb’s pad “finger print” flatly pressed to the rest). The Align Tactical® THUMB REST TAKEDOWN LEVER protrudes 0.4 inches (10mm) from the grip module for a comfortably slim footprint that creates approximately half a thumb width of effective resistance area. Horizontal serrations offer excellent traction against recoiling muzzle rise without being abrasive. Perfectly sized with aesthetics to match. The Align Tactical® THUMB REST TAKEDOWN LEVER is compatible with all models of Sig Sauer® P320 (M17/M18)® pistols. Hardened S7 tool steel part finished in Black Oxide. Approved for USPSA Production. Made in USA with lifetime warranty. *Holster selection requires clearance for extended ledge. |

Grayguns Hard Duty Use P320 Magazine Base Pad - Extended
|
Designed for hard-duty use. Our custom Grayguns SIG Sauer P320 magazine base pads are manufactured from 6061 Aluminum. Professionally finished with MIL-A-8625 Type III anodized coating. Pads go through a glass-beading process to provide a flat-black finish. The base pad is the same thickness as the OEM SIG base pad. A relief cut on the sides enhances malfunction drills, and allows for effective one-handed reloads using the belt or holster. The cut mirrors the normal P320 module’s and creates a cut for the X-Series modules. Each pad features a 3-by-5 matrix. Number your mags using a Sharpie or paint pen. Additional space is available to write your initials. Backwards compatible with all versions of P320 modules, including the standard and X-Series with or without the extended magwell installed.
Note: These base pads are compatible with new SIG P320 magazines with the square pegs. |
