Description
Designed for hard-duty use, the custom Grayguns SIG Sauer P320 magazine base pads are manufactured from 6061 Aluminum and professionally finished with MIL-A-8625 Type III anodized coating. In addition, the base pads go through a glass-beading process to provide a flat-black finish.
Appropriate for competition and shooting enthusiasts looking for a quality, durable upgrade.
The base pad is the same thickness as the OEM SIG base pad. We’ve streamlined them in multiple areas. 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 P320 OEM modules and creates a cut for the xSeries 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.
Our base pads are compatible with our P320 Laser-Sculpted Grip Modules and Laser-Sculpted P320 Tungsten-Infused Grip Module.
Backward compatible with all versions of P320 modules, including the standard and xSeries, with or without the extended magwell installed.
P320 Base Pad Fit Guide
IMPORTANT—In 2024, SIG changed the “wing flanges” where base pads slide onto the magazine’s base. This increased the overall width by three-hundredths of an inch. Our base pads are made to exacting standards, and they will not fit on the newer magazines without alteration to the magazines.
Please check the width of your magazines at the wing flange, as shown in the photos. If it is about .9350, you are good to go. If it is .9650, the magazines will need to be fitted. Our next batch (release date to be determined) of base pads will be designed to fit both widths.
Magwells
With the large selection of aftermarket grip modules and magwells available for the P320, it is difficult to know if our base pads will work with modules and magwells from other manufacturers.
- Our Extended Magwell Version does not fit the P320 grip modules from Wilson Combat.
P320 Magazine Base Pad Versions
- Standard Version – Designed for the XSeries without the magwell. It also works with the P320 module.
- Extended Magwell Version – Designed for the full-size magazine in an XSeries module with the magwell. It also works with 21-round magazines and fits the standard P320.
P320 Magazine Base Pad Weights
- Standard Version – 10.1 grams
- Extended Magwell Version – 26.9 grams
Base pads are compatible with new SIG P320 magazines with square pegs. (See product photos.)Â Do you have the base plates with the round peg? If yes, you’ll need to purchase a P320 Inner Base Plate – Square Peg for each of your magazines.

Got the slightly extended base pads to fit the XFIVE frame with magwell. These have a precise fit, solid feel and look great.
Very happy.
Excellent feel and finish. Very tight to install. I had to oil the channel to get the base to slip onto the magazine. These are brand new out of the box Sig magazines.
Great product and happy with my purchase. Looking to replace the base on my 21rd soon.
Great fit and finish! Shipped quickly. Ext. Magwell on M1811 Module is perfect length. Thanks Gray Guns
Put these on the standard mags that came with my 320 xfive legion. These stick down a little farther than the stock ones so they’re way easier to seat.
Fit and finish are spot on – needed these floor plates to convert standard Sig P320 mags to work in an AXG model with extended mag-well. Superior design and thought process went into these floor plates – the converted mags also fit into other P320 variants
Needed to change base plates after a building Sig P320 X5 conversion kit. Customer service knew exactly what I needed over the phone and had it shipped ASAP. Couldn’t be happier with results.
Great base pad, at a good price! Much better than my legion pads, which always seem to come loose dropping on concrete. Have since converted them to these pads
These worked perfect for my P320 mags and fit great in P320. I will have to get a few more for rest of my mags. Great vendor and quick to ship.
I’ve been looking for basepads for my P320 17rnd mags, since Sig decided to make a Magazine Funnel as they call it, that doesn’t work with the mags provided with the gun when purchased. The Extended Magwell base pads worked perfectly. They load smooth and eject the same way. They definitely work with the P320 AXG Magwell. It’s not quite a flush fit, there is just barely enough to get a hold of to pull them out. That hasn’t been an issue for me, as they fall free every time even when empty.
Highly recommended. Quick easy service on ordering and getting. They work perfectly for upgrading standard mag so that they will work perfectly in the x-Five grip module. Again Highly recommended!!!
I ordered the base plate. Upon receipt I observed the product to be well made. Unfortunately, I experienced some fitment issues with my magazine. Gray Guns customer service was on top of the situation and went above and beyond to get me exactly what I needed. Highly recommended. Customer for life.
