Sig P320 X5 Legion Coming

We just shared some exciting news we received on the release of Sig’s P365 XL but that isn’t the only new pistol coming out!

Sig P320 X5 Legion

Sig Sauer also shared news that the next variant in the Legion is the Sig P320 X5. At a quick glance, I’d say it fits perfectly in the Legion series and looks incredible!

What you can’t see in the photo is that this new XFIVE Legion weighs much more than current P320 X5 pistols by a whopping 7.9 ounces (it weighs 43.5 ounces). They accomplished this increase in weight by infusing Tungsten into the grip module. Sig is calling it a TXG Tungsten infused heavy XGrip module.

Since we aren’t expecting to get an all metal grip module, this is definitely the next best thing! To put it into perspective, Walther’s new Q5 Match Steel frame pistol weighs 41.6 oz empty. A P226 X5 Tactical weighs approximately 35.5 oz and a P220 10mm Legion weighs 44 oz so this is just a half ounce lighter.

The X5 Legion will be offered in high capacity and 10rd (AKA the I live in a liberal state version) variant. The high capacity magazine will hold 17 rounds and the base pads are aluminum. The other P320 mags. (17rd and 21rd) should work as well since the height hasn’t changed.

Part numbers:

17rd version: 320X5-9-LEGION-R2 / UPC 798681618286
10rd version: 320X5-9-LEGION-R2-10 / UPC 798681618293

SIG SAUER Introduces Ground-Breaking Innovation with the SIG SAUER P320 XFIVE Legion 

NEWINGTON, N.H., (July 1, 2019) – SIG SAUER, Inc. is pleased to introduce ground-breaking innovation to the P320 pistol, and the expansion of the SIG SAUER Legion Series of pistols with the SIG SAUER P320 XFIVE Legion. The pistol features the exclusive TXG grip module developed by SIG SAUER engineers with a patent-pending process by infusing tungsten into the polymer material providing the weight of steel with the flex of polymer. Additionally, this is the first striker-fired pistol to be introduced to the Legion Series of pistols.

SIG SAUER Introduces Ground-Breaking Innovation with the SIG SAUER P320 XFIVE Legion

“We are really excited about the introduction of the SIG SAUER P320 XFIVE Legion to the market because it embodies the forward-thinking SIG SAUER mindset when it comes to product development,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc.  “The P320 XFIVE Legion is defining innovation and changing the game for competition pistols, and it’s these exclusive features that are designed to enhance the shooting experience that our Legion members have come to expect from us.  The grip module is heavier, substantially reducing felt recoil and muzzle flip, and the newly developed trigger reduces pull weight by up to 30% for a crisp, fast shooting experience – and that’s just the start.”

The SIG SAUER P320 XFIVE is a 9mm striker-fired pistol, with the TXG tungsten infused heavy XGrip module, a Legion Gray PVD Slide with lightening cuts, 5” match grade bull barrel, and a lightened and skeletonized trigger.  The recoil assembly of the P320 XFIVE Legion has been upgraded to include a one-piece stainless steel guide rod and a 14lb. 1911-style spring, plus an extra 12lb. spring, allowing the end user to easily adjust the recoil spring for a customized shooting experience.  The pistol comes optic ready and is compatible with a SIG SAUER Electro-Optics ROMEO1PRO Optic or a standard DeltaPoint Pro Optic, features Dawson Precision® Fiber Optic front and adjustable rear sights, and comes with three 17-round magazines with anodized aluminum Henning Group base pads.

The Legion Series pistols are an exclusive product line developed by SIG SAUER based on input from elite shooting professionals, and designed to exceed the expectations of the serious shooter.  The SIG SAUER Legion is an exclusive members-only access program available to owners of the SIG SAUER Legion Series of firearms.

    Very interested in this pistol, would really like to know more about the SRT, Does the trigger have the same pull and reset with just being cosmetic skeletonized?
    Thanks! JW

  2. Patrick Boyd

    I’m interested in the P320 X5 Legion when it’s available. Also what other calibers will it be available in?

  3. Patrick Boyd

    I have two P320’s a full size and a compact and love both guns. Givinf the wife the compact for her carry gun and planning on buying a compact 45.

  4. Jonathan Powers

    Why???? Why would you make this gun a half ounce too heavy to be an IDPA legal gun? I guess this is for USPSA production division only?

    1. OCG Post author

      The tungsten grip weight weighs about 1.6 ounces and is removable. Just remove it and you should be fine.

  5. Ed

    You have USPSA Grandmasters and IDPA pros at Sig, and you think this gun will not be designed to meet these requirements?

    1. OCG Post author

      Unfortunately we do not anticipate the P320 XFive Legion being added to the Armed Professional Program. Sig did not add the regular P320 X5 to the APP program either.

  6. Don Miller II

    Has there been any indication from Sig that the TXG Tungsten Infused Heavy XGrip Module will be available as an accessory?

    I already have a standard X Five with a tungsten gun rod, 14 lb Wolff Spring, Gray Guns competition trigger/FCU, Romeo1, 21-round mags w/ Springer Precision baseplates. All I need is this new grip module!!


  7. Christopher D Johnson

    I know you don’t have the TXG Grip module in stock yet however do you know if the grip weight will be inserted? I know on Sig’s website, you have to option to purchase the original X-grip with or without the weight. Just curious

      1. Christopher D Johnson

        Roger, thank you! Do you have an expected date these will be in stock and Can i pre-order part number 8900036? I’m ready to show up the Walther Q5SF shooters at my local matches. LOL
