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.

• This the Extended Version Designed for the full-size magazine in a XSeries with the magwell. Also works with 21-round magazines and fits the standard P320.

Note: These base pads are compatible with new SIG P320 magazines with the square pegs.
