P320 +5 Competition Base Pads (Brass)

(1 customer review)


Due to supply issues, raw brass material is VERY limited, so our base pads availability will be VERY limited. Pricing is subject to change at any time.

Our Plus 5 P320 Brass Base Pads are perfect for competitors looking to add weight to their pistol. As compared to our 6061 Aluminum pads with anodized coating the Brass Base Pads are significantly heavier; about triple the weight.

Also available in hard duty 6061 Aluminum.

Discount available when you buy three or more base pads! ($50 each) The discount is shown in the cart prior to checkout.

For USPSA Limited and Carry Optics, ensure you weigh your setup to ensure you are under the maximum weight limit. 

These base pads work with 15, 17 and 21 round P320 9mm magazines. Use your stock magazines springs for the 15 and 21 round magazines, but use the included Wolff Spring for use with the 17-round magazines. For details on .40 and .357 SIG capacity, view the Fit Guide below.

Although these base pads are a bit “softer” and will show scratches and dents with use, we expect the same extra-long service life as our aluminum base pads.

Backwards compatible with all versions of P320 modules, including the standard and xSeries with or without the extended magwell installed. Does not include a magazine.

Designed for hard-duty and competitor use. Our custom Grayguns SIG Sauer P320 9mm Plus 5 Solid Brass magazine base are specifically designed for the competitor looking for more weight.

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

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) is used to hold 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 fully load.
  • These aluminum base pads weigh 3.6 ounces.

    The Best basepads ever!

    dexterml (verified owner)

    I’m just amazed by the quality of these basepads. I use them as my drop mags. They take quite a beating. I love the way they come right out of my P-320 X5 Legion! I can’t wait to use them on my P-320 Lockwood!

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
