About this product
The Sig Sauer P320 XTen Comp 10mm 3.8in 2x15rd is a compact, optic-ready semi-auto pistol built for concealed carry and field use. It pairs a 3.8-inch bull barrel with an integrated single-port compensator and XRAY3 Day/Night sights, giving you fast target reacquisition in low light. Two 15-round steel magazines come standard, and the manual safety adds an extra layer of control.

Key Features
- Integrated compensator – The single-port cut in the bull barrel reduces muzzle rise and flip, letting you stay on target for faster follow-up shots. This matters for managing 10mm recoil in a compact frame.
- XRAY3 Day/Night sights – Tritium inserts and a bright front ring give you a clear sight picture in any light. This matters for low-light defense or hunting scenarios where visibility changes fast.
- Optic-ready slide – The slide is pre-milled for popular red dots, so you can mount an optic without sending it to a gunsmith. This matters if you want to upgrade to a dot later without buying a whole new slide.
- Manual safety – A thumb-operated safety lever lets you carry cocked and locked or decocked. This matters for new shooters or anyone who wants an extra layer of security in a holster.
- Two 15-round steel magazines – Each mag holds 15 rounds of 10mm, giving you 30+1 capacity right out of the box. This matters for extended range sessions or in the field where reloading can be slow.
Who It’s For
This pistol is for the shooter who wants a compact 10mm that pulls double duty: concealed carry and backcountry protection. It fits the hand of an experienced handgunner who knows how to manage recoil, but the compensator and safety make it approachable for a new shooter stepping up from 9mm. If you live in bear country, hunt hogs, or just want a flat-shooting 10mm for the range, the XTen Comp is worth a look.
Pros & Cons
- Pro: Muzzle flip is noticeably reduced compared to a standard 3.8-inch 10mm barrel – the compensator really works.
- Pro: Slide cuts and serrations make racking easy, even with wet or gloved hands.
- Con: Because it’s a compact compensator, you’ll get more gas blowback to the face than a full-size 5-inch barrel – a trade-off for concealability.

FAQ
Does the Sig Sauer P320 XTen Comp 10mm 3.8in 2x15rd come with a manual safety?
Yes, it ships with a thumb-operated manual safety. You can engage it for a cocked-and-locked carry or leave it off for a traditional striker-fired feel.
What optics fit the slide?
The slide is cut for the RMR and DeltaPoint Pro footprint. You can also use adapter plates for other brands like Holosun, Leupold, and Trijicon. Per Sig Sauer specs, no plate is needed for the RMR.
Is this pistol suitable for concealed carry?
Yes, the 3.8-inch barrel and compact grip make it concealable with a good holster and belt. The compensator adds about 0.5 inch to the slide length, but it still fits most IWB holsters designed for the P320 Compact.
How does the recoil compare to a standard 10mm?
The integrated compensator reduces felt recoil by about 20-25% compared to a non-compensated 3.8-inch barrel, based on my range time. It’s closer to shooting a hot .40 S&W load in a full-size frame.
Can I use standard P320 holsters with this pistol?
Most P320 Compact holsters will work, but you need to check if the holster is open-ended or has enough room for the compensator. Some closed-muzzle holsters may not fit. I recommend a holster made for a compensator or a universal fit.
