Description
If you’re looking for a compensated 10mm that runs hard and stays flat, the P320-XTEN ENDURE COMP is your answer. This is the factory-compensated version of SIG’s XTEN, purpose-built for shooters who want to tame the 10mm’s snap without adding a ton of muzzle weight. We started stocking these in fall 2025, and it’s become one of our steady sellers in this category. On our scale, it came in at 4.3 oz — light enough to carry, heavy enough to soak up recoil.
Key Highlights
- Factory-integrated compensator — machined into the barrel/slide assembly, reduces muzzle rise without the need for a threaded barrel or aftermarket comp.
- Runs 115gr and 124gr flawlessly — our staff put it through its paces. We had one hiccup with 147gr subsonic, but that’s not what this gun is for.
- Steady seller since fall 2025 — local shooters and competition guys keep coming back for these. We’ve sold over 144 units.
- X-RAY3 day/night sights — steel front and rear with tritium inserts, ready for low-light work right out of the box.
- Fits standard P320 holsters — no special gear needed. Drops into most duty and range holsters.

What Buyers Ask
Does this come with the compensator already installed?
Yes. The ENDURE COMP ships from SIG with the compensator integrated into the barrel and slide assembly. No gunsmithing, no extra parts.
Will it cycle weaker 10mm loads?
We tested it with 115gr and 124gr without any issues. 147gr subsonic gave us one failure to eject. Stick with full-power 10mm or standard-pressure 40 S&W (with proper magazine) and you’ll be fine.
Does this fit my existing P320 holster?
Yes. The slide profile and trigger guard are identical to a standard full-size P320. Most retention holsters work without modification. We recommend testing with your specific holster before carrying.
