P320-XTEN Magwell with Magazine Base Pads

(19 customer reviews)

$99.00

The custom Grayguns SIG Sauer® P320-XTEN Magwell includes two (2) heavy-duty custom base pads.

Wide magwells are designed to allow the user to load their pistol quickly. The Grayguns design extends only about 3/8 of an inch, making it practical and not too big. The P320-XTEN magwell is machined in-house by the Grayguns team from 6061 Aluminum and then finished with a Type II hard anodized coating.

Read our Fit Guide below if you intend to mix and match with 45 ACP magazines or modules.

If you already have our magwell, you can purchase additional P320-XTEN Hard Duty Extended Base Pads.

Description

The practical design of the Grayguns P320-XTEN Magwell flairs, creating a wider opening for inserting your magazine. Magwells have been used for years by competitors to make it easier to load magazines. This magwell is appropriate for competition, duty or carry.

The magwell will slip on without modifications to the P320-XTEN’s grip module.

P320-XTEN Magwell Specifications

  • Machined in-house out of 6061 Aluminum, finished in Type III hard anodized coating in black to match OEM stock grip module.
  • Extends out about 3/8 of an inch
  • Designed specifically to work with our P320-XTEN Hard Duty Extended Base Pads

Components Included

  • Custom-designed magwell
  • Two (2) Grayguns P320-XTEN Hard Duty Extended Base Pads
  • 5-40 screw
  • Polytetrafluoroethylene (PTFE) Nickel coated tool steel retaining nut

Fit Guide

  • The magwell is specifically designed for the SIG P320-XTEN 10mm.
  • Our magazine base pads are designed for the SIG OEM magazines provided with your pistol.
  • The magazines will not work on the 45 ACP grip module with the magwell installed.
  • If you intend to use these base pads with 45 ACP magazines, you must have the square, 10mm inner base plates.
  • Your OEM P320-XTEN base pads can not be used with a magwell. They are designed for the OEM module and incompatible with an extended magwell. (This is why we provide you with two of our base pads in this kit.)
  • We do not test the fit with third-party magwells or grip modules from other sources.

The 10mm and 45 ACP versions of the P320 use different grip modules. Both are wider and deeper than the 9mm, .40 cal and .357 SIG versions. The fire control units are also different. Ensure compatibility before mixing and matching components.

  1. I ordered this set-up for my 320x-10 comp. Perfect fit and super easy install. This was a great upgrade for a gun that is already awesome. Looks like it came from the factory. The baseplates add just enough weight. I’m very pleased with my purchase. Thank you.

  3. Grayguns is the best option to upgrade 10mm/.45acp P320s. The parts are top tier and combine with the gun seamlessly.

  4. This project works great in helping me keep a firm grip on the XTen, which can have some tremendous recoil when shooting full load ammunition. Also, Grayguns has exceptional customer service. When I contacted them about a problem with the installation screw, Chris from customer service immediately sent me a replacement which fixed the issue.

  5. Let’s face it the XTen doesn’t have a ton of aftermarket support but Greyguns has come through for us and the fit and finish of the mag well and the base plates is perfect.

  6. If you think your pistol is perfect out of the box, it’s not. This magwelll makes it perfect. I absolutely love the feel! Magwell fits solid and looks great. The fllare of the magwell fits my hand perfectly and steadies me up. I highly recommend this to anyone.

  8. Guess I was one of the lucky few that was able to get this part for my XTEN, also ordered 2 additional bases, perfect fit on all parts, I had also got a bronze grip module and Grayguns trigger assembly made this 10mm stand out, also made it a better firearm than from the factory, the factory trigger left a lot to be desired, now it is crisp and very flat on follow ups.

  10. I made sure that the magwell was available & in stock before I purchased the pistol. I was pleased that not only was the price reasonable, but that it also came with base pads. I normally replace anything plastic that can be upgraded, but in particular the basepads/mag extensions. Not sure why anyone getting a magwell wouldn’t expect to swap them out, but I don’t particularly like jigsaw pattern/snaggletooth look when mags meet pistols. The magwell is clean, smooth & functional and for me, gives a better repeatable grip each time it’s held. The Xten is incomplete without this upgrade.

  12. Signed up on the wait list and it only took like 2 weeks to be notified of stock. The magwell is precision machined to a tight fit. It took me less than 5 seconds to find the sweet spot it inserting it to the grip module: lip towards the business end first then the rest (backstrap end) is pressed hard into place. Snaps into place nice and tight, then insert the threaded block and fasten screw (and add a little threadlocker). No mods needed. 🙂
    The baseplates are sturdy and feels solid without causing the whole handgun to be grip heavy.

    These GrayGuns XTEN parts were designed as if it was always meant to complete this P320 XTEN.
    BTW, extremely fast process and shipping. That is how business should be done. Thank you.
