Full-power 10mm in a pistol you can comfortably carry all day has always been a bit of a compromise. Sig tackled that head-on with the P320 XTen Carry Comp. Instead of hanging a bulky compensator off the muzzle, they machined a single-port expansion chamber directly into the slide, just ahead of the 3.8 inch bull barrel. The slide is the same length you would find on a 4.25 inch P320, so it holsters like a standard carry gun, but that integrated port vents gas upward to fight muzzle flip. Sig puts the recoil reduction at around 20 percent, and side-by-side testing against other compact 10mm pistols consistently ranks this one as the softest shooting of the bunch. Follow-up shots come back on target noticeably faster than you would expect from this cartridge.
This is a striker-fired P320 through and through, running the modular fire control unit inside an XSeries carry-length grip module sized for the 10mm/45 frame. The flat XSeries trigger breaks clean, the Nitron-finished stainless slide is cut for a red dot, and XRAY3 day/night sights handle things until you mount an optic. A Picatinny rail up front takes a light or laser without fuss. This version ships with two 10-round steel magazines for a 10+1 capacity. There is no manual safety to slow you down, just a consistent trigger press every time.
Sig built this pistol with backcountry hunters, anglers, and hikers in mind, and it fits that role well. The 10mm Auto brings serious energy for animal defense in bear country, and the compensated slide keeps that power manageable when seconds matter. It also makes a strong trail-to-range crossover gun, since the reduced muzzle flip turns extended practice sessions from a chore into something you look forward to. One thing worth knowing: parts and accessories from 9mm, .357 SIG, and .40 P320s do not interchange here, so stick with 10mm and .45 components. If you have been waiting for a 10mm that carries like a 9 and shoots softer than most of its rivals, this is the one to handle.
Sig rates the combination of the single-port expansion chamber and the 3.8 inch bull barrel at roughly a 20 percent reduction in felt recoil and muzzle flip. Since the port is machined into the slide rather than threaded onto the barrel, the gun stays the same overall length as a standard 4.25 inch slide P320. In practical terms, it shoots noticeably softer than most other compact 10mm pistols in its class.
Yes, the Nitron slide comes with a removable cover plate for direct mounting of a red dot. Sig designed the cut around the ROMEO2, and optics sharing that mounting pattern, like the Trijicon RMR footprint, will work. Just make sure whatever optic you choose is rated for 10mm recoil, since lighter-duty dots can struggle on this cartridge.
No, and this trips people up. The XTen is built on the larger 10mm/45 frame size, so grip modules, slides, and magazines from 9mm, .357 SIG, or .40 P320s will not interchange. Only 10mm and .45 XTen-pattern components are compatible with this pistol.
Sig built it with backcountry use in mind, think bear country hikes, hunting camps, and fishing trips where you want serious stopping power in a holster-friendly package. This particular SKU ships with two 10-round magazines for a 10+1 capacity. The soft-shooting compensated slide also makes it a great range gun for anyone who wants to run 10mm without the usual beating.
