SIG SAUER P320-XTEN COMP 10mm 10-Round Pistol

Description

SIG SAUER P320-XTEN COMP 10mm 10-Round Pistol

The SIG SAUER P320-XTEN COMP combines the power of 10mm Auto with a carry-length XSeries configuration and an integrated expansion chamber. Manufacturer part number 320XCA10COMP10 and UPC 798681697700 identify this exact 10-round, optic-ready variant. It uses a 3.8-inch bull barrel, black Nitron-finished slide, XRAY3 day/night sights and a black polymer XSeries carry grip module.

Integrated compensation in a carry-length package

SIG SAUER developed the XTEN COMP around a single-port expansion chamber integrated into the front of the slide. The slide is approximately the length associated with a 4.25-inch barrel, but the internal 3.8-inch bull barrel leaves space for the expansion chamber. SIG SAUER reports that the ported-slide and bull-barrel combination reduces felt recoil by approximately 20 percent compared with an uncompensated configuration.

The manufacturer lists the P320-XTEN COMP family at 7.6 inches long, 1.4 inches wide and 5.6 inches high, with a weight of 32.3 ounces including a magazine. Its shorter overall length distinguishes it from the original 5-inch P320-XTEN while retaining a grip designed for 10mm Auto and .45 Auto dimensions.

XSeries controls and grip

The pistol is striker fired and uses a flat XSeries trigger with a 90-degree break. The carry-length polymer grip module incorporates the XSeries profile, including an extended beavertail, undercut trigger guard and textured gripping surfaces. A Picatinny-style accessory rail provides space for compatible lights or other equipment.

This exact catalog configuration is listed without a manual safety. A suitable holster must completely protect the trigger and must be specifically compatible with the wider XTEN COMP slide, integrated expansion chamber and any installed optic or rail accessory. Do not assume that a holster made for a standard 9mm P320 Carry will provide the correct fit.

Optic-ready slide and XRAY3 sights

The Nitron-finished stainless-steel slide has front and rear serrations, XRAY3 day/night sights and a PRO optic-ready footprint. SIG SAUER specifically identifies the ROMEO2 and ROMEO-X Pro among the optics suited to the XTEN COMP. An electro-optic is not included with this SKU. Before mounting any sight, confirm footprint compatibility and follow the optic and pistol manufacturers’ screw and torque instructions.

10-round configuration

Part number 320XCA10COMP10 is the 10-round version of the P320-XTEN COMP. It is intended for buyers who need or prefer restricted-capacity magazines. Do not confuse it with otherwise similar 15-round XTEN COMP packages or optic-equipped variants. Magazine limits and transfer requirements vary by jurisdiction, so confirm local eligibility before ordering.
