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 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.

Haven’t been able to use these in the field yet, but they seem very solid. Finish is excellent. I LOVE the dimples for numbering the pads. Very clean and a medium white paint marker worked flawlessly. The one change I would make is to increase the grip undercut a bit for use with gloves. I may add some skateboard deck tape to the sides of mine.
I’m going to be sad watching these slam into gravel on ranges, but I know they will protect the working parts of the magazines!

Got a Sig P320 Legion with the extended magwell & needed to replace my old 17 round magazine base pads. These were less expensive than all others I found, with the discount for multiple items. Well recommended & reviewed. They work great with all of my P320 grip modules, which unfortunately the Legion base pads did not.

I bought these so that I could could continue to use my old 17rd magazines with the new flared magwell I installed on my p320.
The fit and finish are great, and they work for the intended purpose. The price was reasonable, however for my (non-competition) use case, it would have been nice to see a cheaper polymer option.
Overall, great product!

Ordered the P320 Mag extensions for my standard 17 round mags. The original mags fit great in my 320, not so good in my legion… these basepads fixed that. They are +0 but that is fine as they actually fit now!!!
The Legion is designed to work with the 20 round sig mags, but these baseplates saved me the cost of some new mags. The 17 rounders now fit my 320 and my legion!!
Thank you.

Easy to install, performs as advertised.
As a bonus, empty mags seem to drop free easier.

Excellent product! My stock base pads had worn and shifted around exposing the sharp edge of the magazine, these aluminum base plates are a great solution.
Parts received were very clean and high quality.
Fit is perfect and installation is a breeze.

I had gotten a Magwell for my xgrip and had to change my baseplates. So i purchased these and they feel amazing and look amazing too. Coupling these up with my xgrip and flared magwell make for very fast easy reloads.

Bought these so my 17 round mags will fit with the Sig Mag well funnel. The work great and add just a little extra weight so when you hit the mag release they fall free without a worry. I no longer worry about my base plates breaking when the magazine lands on concrete or a rock.

I have both the single base pad and the base pad for magwell. Both are great fitting, add weight and look better than the legion base pad or any other on the market. The engraving option is a great touch to personalize and mark each magazine.

I’ve been running these GG +0 extended base pads for IDPA and they work great with the AXG flared magwell extension! I ran the ones that SIG included with the gun, and while I like the aggressive texture on those, they are almost completely flush when seated which can make it difficult to seat the mag completely when pressured by time. The GG + 0’s stick out of the bottom of the flared magwell extension just enough to eliminate that for me. I most certainly reccomend them!

Let’s face it, the stock p320 base plates stink. I switched them out with the Gray Guns square base pads to accommodate a magwell. They look great and function even better. Fantastic quality.

I have purchased 12 of these base pads for use with a Sig P320 with a magazine funnel attached. Happy to say that they fit and work great, no issues at all. Work so well had to get 6 for my neighbor.

Great weight, works perfectly, if your buying a normal p320 magazine, put this plate on it.

Just what you need if adding a extended magwell. $55.00 for Legion mag, or $18.00 for this. Fits perfect, works perfect and looks fantastic. Thanks Grayguns for another outstanding product.

Purchased several of these base pads for my Xcarry Legion. I purchased some aftermarket P320 17 round magazines with base pads that do not fit the Xcarry frame with or without the mag well. These base pads work perfect and seem better than the original Legion mag’s base plates which are dent, scratch, and show wear immediately. Price is right also. I only purchased a few to see how they work and intend to purchase several more to round out the new purchased mags.
Thanks.

I just received and placed into service my P320 Hard Duty Use base pads. I ordered a dozen with the laser marking. They were produced and shipped immediately. In hand the base pads are fantastic, obviously as strong as advertised. Additionally, they have a nice little recess built in for one to tug at the mag to be sure it is seated or to rip when necessary. These base pads are a product that improves both function and appearance, and what’s not to like about that?!
Thank you, Grayguns, for an outstanding product!

I purchased the Hard Duty Use SIG P320 Magazine Base Pads for my SIG P320 X-Series compact build. Their fit and shape are exactly what I was looking for in this grip module. The slight extended relief cut allows for a positive grab but not enough to cause excess printing for EDC. Definitely love the aesthetic appearance of the base plate for my pistol.

I shoot IDPA and these base pads are the perfect addition when you run a magwell but need to still fit in the box. It’s a touch of class that you can get these custom engraved.

Honestly blown away when I felt the quality of these base pads!
For some reason I expected them to be plastic for the price and forgot they were aluminum in the description… I was pleasantly surprised.
Bought these to replace my standard Sig 17 rd mag base pads, so that I could use them with the extended mag well.
VERY happy with purchase!

I picked one up for my carry RXP X-Compact. It mates perfectly with the 15rd mag in the gray laser sculpted grip module. The tolerances to the mag body are outstanding. They are far superior to the shield arms +5 extension that has slight gaps around the mag body rails. Both pads function flawlessly but this pad looks like it was hand fitted, like a nice 1911. Pretty solid deal for a low price. My p320 ccw mags will all wear these moving forward. Thanks again GGI, I’ll be back.

I bought 10 of these for competitive shooting. They are extremely well made and very durable. I especially got them for the inlays for numbering my mags. I have nothing but great things to say. Be advised that if you have purchased Extended Magwell Version for your 21 round magazine they will not meet USPSA mag length. I shot at the USPSA 2019 Area 7 championship and found out the hard way at the crono stage. The 21 rnd mags with the GG Extended Magwell Version will not pass the 141.5 mm. I was moved to Open division from Carry Optics.
