Description
The P320-SXG RESERVE is a factory-built competition pistol from SIG Sauer, designed for shooters who demand precision out of the box. It pairs the proven P320 fire-control unit with a steel grip module and a 5-inch bull barrel, delivering a flat-shooting, low-recoil platform for USPSA, steel challenge, or range work. We’ve had these on our shelves since mid-2024, and the return rate is low—customers get exactly what they expect. One thing we noticed right away: the weight is barely noticeable once installed. On our scale, the complete pistol comes in at 6.6 oz lighter than you’d think for a steel-framed gun this size.
Key Highlights
- Steel Grip Module: Reduces muzzle flip and speeds up follow-up shots without the bulk of a full dust-cover frame.
- 5-Inch Bull Barrel: No bushing, no play—just consistent lockup and accuracy round after round.
- Flat Trigger: Clean break with a short reset; adjustable over-travel stop included.
- Optics-Ready Slide: Cut for RMR, DPP, and DeltaPoint Pro footprints. Includes cover plate.
- Factory Tuned: Trigger pull measured at 4.5 lb on our gauge. Ready to shoot right out of the case.

What Buyers Ask
Does this fit standard P320 holsters?
Because of the steel grip module and bull barrel, the SXG RESERVE is wider at the frame and longer up front. Most standard P320 holsters won’t work. You’ll need a holster specifically made for the SXG or a custom kydex rig. We recommend the Red Hill Tactical SXG holster—we stock those too.
Can I swap the grip module for a plastic one?
Yes, the fire-control unit is standard P320, so you can drop it into any P320 grip module. But the whole point of the SXG is that steel frame. If you swap it, you lose the balance and recoil control this gun is known for. Most guys leave it as-is.
Is this legal in my state?
We ship to all states where P320s are legal. If you’re in a state with magazine capacity limits, let us know at checkout and we’ll ship with 10-round mags. No extra charge. We’ll also remove the threaded barrel if your state bans them—just add a note to your order.
