Sig Sauer XFULL-SIZE: Tactical 9mm Pistol with XSeries Grip

When you’re evaluating a duty-grade 9mm pistol for duty, competition, or personal defense, you look for a combination of ergonomics, sighting options, and a trigger that lets you shoot accurately under pressure. Performance under stress isn’t just marketing copy — it’s built from parts that work together: slide geometry, trigger feel, sight picture, and magazine capacity that keeps you in the fight.

SIG SAUER P320 RXP XFULL-SIZE delivers a modern striker-fired platform with features that matter on the range and in a duty holster. It features the Straight XSeries Trigger which gives a clean, straight 90-degree break for predictable follow-up shots. The slide is nitron coated and optic-ready, including a removable night sight plate and an X-Ray3 front night sight for low-light acquisition. XSeries enhanced slide serrations provide positive purchase when manipulating the slide, and the pistol ships with two 17-round steel magazines — a capability edge when capacity counts. At $979.99, it positions itself as a feature-rich option for shooters who want a robust, optics-ready full-size platform. Shop this product

Design and Ergonomics

SIG SAUER P320 RXP XFULL-SIZE was laid out with ergonomics and modularity in mind. The XSeries grip geometry helps center the hand and promotes a consistent wrist angle, which reduces muzzle flip during rapid strings. The full-size frame gives a longer sight radius, which helps precision at extended distances compared with compact models. XSeries enhanced slide serrations are deeper and more aggressive than stock serrations on older designs, making press checks, slide racking, and manipulations more positive in wet or gloved conditions.

Trigger and Controls

The Straight XSeries Trigger provides a straight-back pull with a distinct 90-degree break that many shooters find intuitive. That clean break reduces anticipation and helps shooters maintain sight alignment through the press. Controls on the SIG SAUER P320 RXP XFULL-SIZE are laid out to be accessible without overextending the support hand — an important consideration for defensive use. The combination of trigger geometry and grip ergonomics makes for a platform that rewards proper fundamentals.

Sights, Optics, and Slide Features

This pistol’s optic-ready, nitron-coated slide brings modern sighting options to a full-size chassis. The removable night sight plate allows the owner to mount a red dot while retaining the option to reinstall night sights when needed. The included X-Ray3 front night sight offers fast target acquisition in dim conditions and is a popular choice among shooters who want a standout front sight. The nitron finish increases corrosion resistance and reduces glare from the slide when shooting outdoors.

Capacity, Reliability, and Duty Considerations

Two 17-round steel magazines come with the SIG SAUER P320 RXP XFULL-SIZE, providing ample capacity right out of the box. In duty or home defense scenarios, higher capacity magazines reduce the need for immediate reloads. Reliability starts with feed geometry, extractor design, and magazine quality — components SIG Sauer has refined across their P320 series. The full-size frame also helps tame recoil, which aids fast, accurate strings of fire. For agencies or serious private carriers, the combination of two high-capacity mags and an optics-ready slide is a practical setup.

9mm Performance and Applications

Built around the 9mm cartridge, this platform balances controllability, magazine capacity, and ammunition availability. Whether you’re running duty loads or high-performance defensive ammunition, 9mm offers manageable recoil and proven terminal ballistics for close-quarters encounters. For range training, 9mm is affordable and widely available, making it a sensible choice for daily practice.

Range Performance and Maintenance

Shooting the SIG SAUER P320 RXP XFULL-SIZE on the range reveals a platform that rewards consistency. The straight trigger path and the long sight radius of a full-size slide support tighter groups for shooters who practice fundamentals. Maintenance-wise, the nitron slide finish reduces wear on high-contact surfaces, and the optic-ready cut makes sight swaps straightforward. Routine cleaning of the barrel, slide rails, and extractor area will keep the pistol running reliably through thousands of rounds.

Why It Matters

For professionals and serious enthusiasts, SIG SAUER P320 RXP XFULL-SIZE brings together an optics-ready slide, a user-friendly XSeries trigger, and a capacity package that suits duty carry out of the box. The nitron coating, removable night sight plate, and X-Ray3 front sight emphasize readiness for low-light operations and modern optics workflows. At $979.99, it’s positioned to compete with other full-size, feature-packed 9mm pistols while offering a dependable platform backed by a reputable brand. When you want a pistol that favors predictable ergonomics, positive slide manipulation, and the option to run a red dot or night sights, this model should be on your shortlist.
