When gear meets purpose, you feel it the moment you pick it up. The balance, the controls right where they should be, and the confidence that comes from a setup that’s mission-capable without being flashy. This is the kind of full-size sidearm that doesn’t shout—it simply performs.
SIG SAUER P320 RXP XFULL-SIZE delivers that exact vibe: a pre-owned, full-size semi-auto that’s thoughtfully outfitted and ready for hard use right out of the case. It ships with three 21-round magazines, one 17-round magazine, a TLR-1HL weapon light, a Wilson Combat lower, a SilencerCo threaded barrel, and an extra factory lower in the case—an uncommon, well-rounded package at a price point that makes sense for real-world work.

Why this full-size semi-auto stands out
Sig Sauer built its reputation on duty-grade reliability, and the P320 line has become a staple for professionals and responsible citizens alike. As a Semi Auto platform, this XFULL-size variant brings the benefits of a longer sight radius, added weight for recoil control, and more rail real estate for accessories. The RXP lineage is known for being optics-friendly, but this specific pre-owned setup puts emphasis on two things that matter immediately: illumination and modular control.
Pre-owned done right
Not all pre-owned pistols are created equal. This one arrives as a complete, thoughtfully curated kit, not a bare slide and a single mag. You’re getting three 21-round magazines for maximum capacity and one 17-round magazine for slimmer carry or tighter storage. That magazine mix is ideal for training days and range courses—load the 21s for sustained strings, keep the 17 for administrative or bench work. For those who run classes or train in reps, fewer reloads equals more focus on fundamentals.
Lights, grip, and control
The included TLR-1HL weapon light is a proven, duty-grade white light that pushes serious lumens with a tight hotspot and usable spill. It’s simple, rugged, and dependable—exactly what you want when identifying targets in the dark. The switchology is intuitive, allowing momentary or constant-on without gymnastics, and the unit mounts cleanly on the full-length accessory rail.
Equally important is the Wilson Combat lower. In P320-speak, that means a refined grip module—more texture, better contouring, and ergonomics that lock the hand high and tight without unnecessary bulk. The result is practical control during fast strings, improved recoil tracking, and a more consistent purchase under stress or sweat. If you’ve ever reshaped a grip with tape and a soldering iron, you’ll appreciate how much this module gets right from the start.
As a bonus, this package includes an extra factory lower in the case. That gives you options. Want to configure one for duty or home defense and another for concealed carry or training? Swap modules. Prefer to test different backstrap profiles or stipple patterns without committing? You’ve got a clean baseline to work with. Modularity is the P320’s calling card—this kit leans into it.
Suppressor-ready versatility
The SilencerCo threaded barrel is the quiet star of the show. That single component unlocks real versatility—run a compensator for flatter tracking, or add a suppressor for comfort, communication, and neighbor-friendly practice. A quality threaded barrel also means better tolerance control and consistent lockup. Combined with a full-size slide, this setup sits flat in recoil and rewards a solid grip with predictable sight return.
Balance and handling
Full-size pistols earn their keep in stability and shootability. The P320 XFULL frame length delivers both. With the Wilson Combat grip module, the pistol points naturally and settles quickly. Add the TLR-1HL’s forward weight on the rail and you get a bit more muzzle steadiness—subtle, but noticeable during rapid transitions and on small targets. The trigger on the P320 system is straightforward: a clean take-up and a consistent break that promotes accuracy without drama.
Real-world application
Whether you’re building a home-defense pistol, outfitting a training gun, or seeking a capable range partner, this package checks the boxes that matter. The light makes low-light work feasible. The threaded barrel future-proofs your setup for suppressors or comps. The magazine assortment keeps your time efficient on the line. And the modular lowers let you tailor ergonomics to the task at hand without tools or trips to a gunsmith.
Importantly, this listing does not specify caliber. The P320 family commonly appears in popular service calibers, and the platform’s modularity allows caliber flexibility across compatible components. If you plan to integrate existing slides, barrels, or FCUs, confirm your parts compatibility before mixing modules. That’s smart practice with any modular handgun system.
Value play at this price
At $749.99, the value proposition is straightforward. Add up the cost of a full-size duty-ready pistol, a quality weapon light, a threaded barrel from a respected maker, a premium grip module, an extra factory lower, and four magazines—three of them extended. The math favors this pre-owned package by a wide margin. You’re not paying for flashy engraving or limited-edition hype; you’re paying for performance parts that make a difference on the range and in real life.
Category insights: Semi Auto
As a Semi Auto, the platform offers fast reloads, consistent trigger presses, and easy accessory integration. It’s a natural fit for training progression because every rep feeds directly into control, cadence, and sight discipline. With this setup, you get to focus on actual shooting—grip, sights, trigger—without wrestling the tool.
Set up for success
To get the most from this package, build your foundation: dry practice with the light activation to ensure clean manipulations, run controlled pairs to feel the flatness of the threaded barrel and full-size mass, and experiment with both lowers to find your best interface. Then, keep it boring—confirm function, manage maintenance, and track your round count. Consistency and familiarity trump novelty every time.
Who this pistol serves best
- Shooters who want a complete, duty-capable setup without piecing it together part by part
- Home-defense owners who understand the value of a reliable weapon light and higher-capacity magazines
- Range-focused learners who benefit from a stable, flat-shooting full-size frame
- Modularity fans who appreciate having both a Wilson Combat grip module and an extra factory lower in the case
Final thoughts from the range
There’s a certain calm that comes from a sidearm that’s already configured for the work: bright white light, confident grip, suppressor-ready barrel, and magazines that keep you focused on the drill instead of digging for reloads. SIG SAUER P320 RXP XFULL-SIZE shows up ready to earn trust, and that’s what matters. If you’ve been waiting for a full-size package that doesn’t need a shopping list to finish, this is a smart, no-nonsense pick.
