Sig Sauer P320 Xfive Sxg 9MM 5 Stainless 3X21RD Mags
About this product
The Sig Sauer P320 X-Five SXG is a full-size competition and range pistol built around a solid stainless steel grip module rather than Sig's usual polymer frame, paired with a stainless steel slide for a total package weighing close to 50 ounces. At $1,849.99, it's positioned toward the top of the P320 lineup, built specifically for competitive shooting sports like USPSA Carry Optics and Limited Optics divisions.
What does 'SXG' mean, and why steel instead of polymer?
SXG stands for Stainless Steel X Grip - Sig replaced the standard polymer X-Series grip module with a solid stainless steel version, adding substantial weight forward and rearward of the trigger guard to soak up recoil and keep the sights tracking flatter and faster between shots, which matters more in fast-paced competition shooting than in everyday carry.
What are the core specs?
It runs a 5-inch bull barrel, an optics-ready slide with a fiber-optic front sight and adjustable rear sight, a skeletonized flat trigger, and interchangeable 1911-style recoil springs for tuning recoil impulse to different loads. The grip uses aggressive G10 LOK grip panels bonded to the steel module for texture and control.
Sig's X-Five line has a long track record in competitive shooting circles, predating the current X-Series naming on the standard P320 lineup, and the SXG variant represents the newest evolution of that competition-focused design with the added mass and rigidity of an all-steel grip module. Ammunition compatibility is standard 9mm Luger, and the added weight of the steel grip module is particularly noticeable when running hotter competition loads, helping keep the sights on target for faster follow-up shots during a stage. Because it shares the same trigger group and fire control unit design as other P320 models, shooters already familiar with Sig's P320 lineup will find the controls and takedown process familiar despite the significant change in frame material and weight.
Is this a carry pistol or strictly a competition gun?
While it shares the same trigger group and general architecture as Sig's carry-oriented P320 models, the X-Five SXG's size, weight, and 5-inch barrel put it firmly in the range and competition category rather than concealed carry - it's built to be shot fast and flat in a match, not carried discreetly day to day. The full-length single-slot accessory rail supports a weapon light for those using the X-Five SXG in a home-defense or duty role alongside competition use, though its size and weight remain better suited to range and match use than everyday concealed carry. Handling one at a local range or match before buying is worthwhile given the price and the specialized nature of the platform.
What magazines does it use?
It ships with 21-round magazines, which is standard for the X-Five line's competition-focused capacity - well above California's 10-round limit. Confirm with your FFL which magazine capacity you'll actually be permitted to receive before ordering.
How does the purchase process work?
As a firearm, the X-Five SXG ships to a licensed FFL dealer rather than to your home. You'll complete a background check and any required state waiting period before taking possession. Checkout on this site runs through secure checkout, and FFL transfer fees are set separately by the receiving dealer. Confirm the current California roster status of this specific configuration with your FFL as well, since competition-oriented SKUs aren't always the same listing that carries roster approval.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost. You complete the background check and paperwork with the dealer when you pick up.
California buyers: handguns must be on the California roster for delivery to a California FFL, a Firearm Safety Certificate (FSC) and DROS are handled at the dealer, and the 10-day waiting period applies. Out-of-state buyers receive the firearm through their own local FFL under their state's rules.
