Description
If you need a 10mm that can pull double duty as a range blaster and a compact carry piece, the Sig Sauer P320 XTEN Carry Comp 10mm 3.8″ MS Black is the answer. This is a factory-compensated, carry-length X-Series pistol that fits inside an apartment safe or on your hip without the muzzle flip you expect from a 10mm. It ships with two 10-round steel magazines, an optic-ready slide, and a manual safety for urban CCW holders who want control over every round.

Key Features That Matter for City Carry
- Integrated Slide Compensator: The compensator is milled directly into the 3.8-inch bull barrel, not a bolt-on add-on. This reduces muzzle rise by roughly 25% in 10mm loads, letting you get back on target faster for follow-up shots in tight spaces like a hallway or parking garage.
- Optic-Ready Slide with SIG PRO RX Footprint: No adapter plates needed. You can mount a Romeo2 or other RX-pattern red dot directly to the slide, which keeps the deck height low for concealed carry under a jacket or untucked shirt.
- XRAY3 Day/Night Sights: Tritium front and rear with a bright green ring. These are steel and do not require batteries, so your sight picture stays consistent even if your red dot fails or the glass gets occluded during a defensive encounter.
- Flat XSeries Trigger (90-degree break): The trigger breaks clean at roughly 4.5 pounds with a short reset. That predictable wall helps you avoid jerking the trigger under stress—critical when you’re shooting a high-pressure 10mm round.
- Manual Safety on Fire Control Unit: The FCU ships with a manual safety lever installed, but you can remove it if you prefer a consistent draw without extra steps. This flexibility matters for apartment dwellers who store the gun loaded and want an extra layer of security.
Who This Gun Is For
This pistol is built for the urban CCW holder who wants 10mm power without the full-size footprint. If you live in a studio or one-bedroom apartment, the 3.8-inch barrel and compact grip make it easier to stow in a nightstand drawer, small safe, or cross-body bag. It also suits shooters who reload or carry hard-cast 10mm for woods defense but still need a concealable platform for daily carry in the city.
Pros and Cons
Pros: Factory-compensated slide reduces muzzle flip noticeably. Optic-ready without extra plates. Manual safety included for those who want it. Uses standard P320 holsters and mags. Bull barrel adds accuracy and durability.
Cons: The 10-round magazine capacity is limited compared to 9mm alternatives like the P320 X-Compact, and the compensator makes the slide slightly longer than the standard Carry model, which may require a different holster cut for some IWB rigs.

The XTEN Carry Comp gives you 10mm power and a factory comp at half the price of custom builds. The trade-off is lower capacity—10 rounds vs. 17 in 9mm competitors—but you gain terminal performance that matters against larger threats or barriers.
FAQ
Does the Sig Sauer P320 XTEN Carry Comp fit standard P320 holsters?
Yes. The slide dimensions are the same as the P320 Carry model, so it fits most standard P320 holsters. However, because of the integrated compensator, some holsters with tight muzzle channels may need a slight break-in period or light sanding if the comp creates friction. Test fit before carrying.
Can I remove the manual safety on this model?
Yes. The manual safety is installed on the fire control unit (FCU) and can be removed by a qualified gunsmith or by swapping the FCU. Sig Sauer sells FCUs without the safety cutout if you want a completely clean grip module. You can also buy a safety delete lever if you decide later you want it back.
What optics fit the SIG PRO RX footprint?
The SIG PRO RX footprint accepts the Sig Sauer Romeo2, Romeo1 Pro, and Leupold DeltaPoint Pro. Some aftermarket plates allow you to mount Holosun 407K/507K optics, but direct mount is limited to SIG and DPP-pattern dots. Per Sig Sauer specs, the slide is pre-milled for no-plate mounting of these optics.
Is the compensator effective with standard 10mm loads?
Yes. The comp is designed to work with 10mm Auto pressures, including standard 180-grain FMJ loads. It reduces muzzle rise by about 20-25% compared to a non-comped P320 in 10mm. With hot handloads or Underwood 155-grain XTPs, the compensation is even more noticeable because of higher gas volume.
