Description

Looking for Hard Duty Use base pads for your SIG Sauer® P320 that will fit an extra five rounds of 9mm? These base pads work with 15, 17 and 21-round P320 9mm magazines. Use your stock magazine springs for the 15 and 21-round magazines, but use the included Wolff Spring for the 17-round magazines. View the Fit Guide below for details on .40 and .357 SIG capacity.

Professionally finished with MIL-A-8625 Type III anodized coating. Pads go through a glass-beading process to provide a flat-black finish.

These custom Grayguns base pads have been built for competition, military and law enforcement use. Designed to be repeatedly dropped on concrete or asphalt hundreds of times, they are a perfect upgrade for the OEM plastic pads.

Our base pads are compatible with our P320 xSeries Laser-Sculpted Grip Module and xCompact Grip Modules.

Backward compatible with P320 modules, including the standard and xSeries, with or without the extended magwell installed.

These base pads will not fit P320 X-TEN magazines. We do offer base pads for the P320 X-TEN.

For those with .40 and .357 SIG magazines. these extended base pads will be plus three instead of plus five. With aftermarket followers, you may be able to get plus four.

Product Notes

  • UPSPA Length – The 17-round magazines with our +5 base pads will fit the 141.25 mm size limit for Limited and Carry Optics
  • No base plate is required, as the back plate (shown) holds the base pad in place.
  • The last round is pretty tough to load on the 17-round magazines; we suggest you use a loader. The 15 and 21-round magazines are easier to load fully.
  • These aluminum base pads weigh 1.2 ounces.
  • We do not test the fit with third-party magwells or grip modules from other sources.

Installation Instructions

These base pads are designed for use without an OEM inner base plate. Remove the inner base plate and have the magazine spring sit directly within the base pad during assembly.

    Perfect weight, quality construction, sleek design, durable, and the laser marking is a cheap add-on. Some machine marks, but nothing to fret about. They shipped fast! I ordered on a Friday and they made it to me by the following Wednesday (Oregon to Chicago), in time for me to use for my weekly shoot night! GrayGuns is doing amazing work over there!!

    I purchased the mag extension for my Sig XCarry’s 3 stock 17rd mags and a 21rd mag. The build quality is great! Very heavy duty,and they came with new springs to accommodate the change. Thanks Gray Guns!
