Description
The P320-XTEN COMP is a factory-compensated 10mm Auto pistol built for shooters who want to tame the recoil of a heavy-hitting cartridge without adding a bulky aftermarket brake. This is a full-size SIG Sauer P320 with an integrated compensator milled into the slide, reducing muzzle rise and keeping you on target for faster follow-up shots. We added this to our catalog in Q4 2025, and it’s been a reliable seller with consistently positive customer feedback — our staff tested it and found it feeds reliably with both brass and steel case ammunition. If you need a duty-ready or competition 10mm that handles hot loads and stays flat, this is your rig.

What Buyers Ask
Does the compensator affect reliability with different ammo?
We’ve run both brass and steel case through this gun in our shop testing — no malfunctions. The compensator is machined into the slide, so there’s no added barrel weight or moving parts to gum up. Stick with factory loads and you’re good.
Can I mount a red dot without buying a new slide?
Yes — the slide comes optic-ready with a removable rear plate. You’ll need the correct adapter plate for your chosen optic (RMR, DPP, etc.), but no gunsmithing is required.
Is this legal to ship to my state?
We ship to FFLs in all 50 states. Some states have magazine capacity restrictions — if your state limits to 10 rounds, we’ll include compliant magazines. Just confirm with your FFL before ordering.
