These Hard Duty Extended Base Pads are specifically designed for the SIG P320-XTEN 10mm and 45 ACP magazines with square base plates.

If you want an extended magwell for your XTEN, we suggest our magwell kit, which includes two hard-duty extended base pads.

P320-XTEN Extended Base Pad Specifications

  • Machined in-house out of 6061 Aluminum
  • Finished in Type III hard anodized coating, in black to match OEM stock grip module
  • They are designed with compatibility in mind for our P320-XTEN Magwell. We do not test the fit with third-party magwells or grip modules from other sources.

P320-XTEN Extended Base Pad Fit Guide

These base pads are specific to the P320 X-TEN and P320 45 ACP with square base plates. If you intend to use these base pads with 45 ACP magazines, you must have the square, 10mm inner base plates.

The 10mm and 45 ACP versions of the P320 use a wider and deeper magwell and magazines compared to the 9mm, .40 cal and .357 SIG versions. The fire control units are also different.

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.
