About this product
The Sig Sauer P320 XTEN Comp 10mm 15rd Black is a striker-fired, compact carry pistol that brings serious 10mm power to a package designed for shootability. This model integrates an optic-ready slide with a factory-installed slide compensator, giving you reduced muzzle rise and faster follow-up shots without adding length. It ships with two 15-round magazines and XRAY3 day/night sights, making it a ready-to-run option for backcountry carry, duty, or home defense. According to Sig Sauer specs, the compensator reduces recoil impulse by approximately 20 percent compared to a standard P320 10mm barrel, a measurable advantage when you need to stay on target.

Key Features
- Integrated Slide Compensator — Why it matters: Reduces muzzle rise and felt recoil, letting you keep your sights on target for faster, more accurate strings of fire. This is especially valuable with the 10mm’s sharp recoil impulse.
- Optic-Ready Slide with Serrations — Why it matters: You can mount your preferred red dot without sending the slide to a gunsmith, and the deep serrations give you a positive grip for press checks or one-handed manipulations.
- XSeries Polymer Grip Module — Why it matters: The high-traction texture and ergonomic palm swell help you maintain a consistent grip under recoil or in wet conditions, common when carrying in the backcountry.
- XRAY3 Day/Night Sights — Why it matters: Tritium inserts and a bright front ring give you a clear sight picture in low light or total darkness, with no batteries to fail.
- 15-Round Capacity (Two Magazines Included) — Why it matters: You get two 15-round magazines out of the box, giving you 31 rounds on your belt for extended engagements or animal defense scenarios.
Who It's For
This pistol is built for shooters who want a 10mm that handles like a 9mm. It’s ideal for backcountry hikers, hunters, and anyone who carries in bear or mountain lion country. It also suits tactical shooters who want a compensated pistol without the hassle of an aftermarket barrel or slide work. New shooters stepping up to 10mm will appreciate the reduced recoil, while experienced shooters will value the factory reliability and optic readiness.
Pros & Cons
- Pro: Factory-installed compensator saves you money and gunsmithing time.
- Pro: Optic-ready slide works with most popular red dot footprints.
- Pro: XRAY3 sights are some of the best factory night sights on the market.
- Con: The compensator adds muzzle weight and may require a holster with an open end for proper fit. Not all duty holsters will accept it.

Frequently Asked Questions
Does the P320 XTEN Comp accept standard P320 holsters?
Most standard P320 holsters will work, but you need a holster with an open or cut-out muzzle end to accommodate the compensator. Many kydex and leather holsters designed for full-size P320s will fit, but always check the manufacturer’s compatibility list before ordering.
Can I remove the compensator and use a standard barrel?
No. The compensator is permanently integrated into the slide assembly. You cannot swap it for a standard barrel without replacing the entire slide. If you want a non-compensated P320 10mm, look at the standard P320 XTEN model.
What red dot footprints does the optic-ready slide accept?
The slide is cut for the SIG ROMEO1 Pro footprint, which also accepts the Delta Point Pro and other optics using that pattern. Adapter plates are available for RMR and other footprints from third-party manufacturers.
Is this pistol legal for hunting in states that require 10mm?
Yes. The 10mm cartridge is legal for deer and predator hunting in most states that allow handgun hunting. Check your local regulations for barrel length and magazine capacity restrictions.
Does the compensator affect reliability with different ammunition?
Per Sig Sauer specs, the compensator is designed to function with full-power 10mm loads. Underpowered or “light” target loads may not cycle reliably due to reduced gas pressure. For best results, use ammunition with a muzzle velocity of 1200 fps or higher.
