SIG SAUER P320-XFULL 9mm Pistol with ROMEO-X SIG-LOC PRO

SIG SAUER P320-XFULL with ROMEO-X SIG-LOC PRO

This P320-XFULL combines a full-size 9mm P320 X-Series pistol with a factory-installed ROMEO-X SIG-LOC PRO optic. Manufacturer part number 320XF-9-BXR3-RXSL identifies the 4.7-inch-barrel configuration with two 17-round steel magazines and XRAY3 day/night sights. It is a specific optic-equipped model, not the otherwise similar iron-sight-only XFULL or a ROMEO-X PRO version. The SIG-LOC PRO mounting configuration is a key distinction when comparing P320 listings.

Full-size X-Series configuration

The 4.7-inch carbon-steel barrel and full-length slide give this model its full-size format. SIG SAUER lists an overall length of 8 inches, width of 1.4 inches, height of 6.4 inches and weight of 30 ounces for this exact SKU. These measurements are most useful for comparing storage space, holster fit and the handling differences between the full-size and compact P320 variants. Check accessory compatibility against the exact optic-equipped configuration rather than assuming that every P320-XFULL shares identical external dimensions.

The Nitron-finished stainless-steel slide is paired with a black XCarry polymer medium grip module and an M1913 accessory rail. Its X flat trigger and striker-fired action are part of the listed X-Series setup. The modular P320 platform permits different configurations, but this product is supplied as the factory combination described here; other grip modules, sights and accessories are not implied to be included.

Factory optic and backup sights

SIG SAUER specifies a ROMEO-X SIG-LOC PRO electro-optic installed on this model, together with XRAY3 day/night sights. The sighting arrangement lets a shopper distinguish this package from listings that are merely optic-ready, and from versions shipped with a different optic. SIG-LOC PRO is the specified RX footprint for this SKU. Before buying a replacement sight, optic plate or holster, verify compatibility with the SIG-LOC PRO version and the factory-installed sight, rather than relying only on the P320-XFULL name.

XRAY3 day/night sights are listed by the manufacturer as the accompanying mechanical sights. This is useful if you prefer a pistol supplied with both an electro-optic and conventional sighting equipment. Consult the documentation for the installed optic for its controls, battery, adjustment and maintenance; those details should not be inferred from similarly named ROMEO-X variants.

Choosing the right P320-XFULL

Within the P320-XFULL family, manufacturer SKUs distinguish magazine capacity, optic model, footprint and other equipment. This listing’s part number is the reliable reference for its two 17-round magazines and installed SIG-LOC PRO optic. If you need a restricted-capacity version, compare the complete manufacturer part number before ordering: the magazines in this package are not the two 10-round magazines supplied with a different SKU. Local laws and transfer requirements may limit where this configuration can be sold.

For fit-related purchases, use the complete model and optic combination when selecting a holster or case. Confirm the intended accessory accommodates the 4.7-inch slide, installed optic and any rail-mounted equipment you plan to use. Read the firearm and optic manuals before use, store the pistol securely, and follow all applicable handling and transfer requirements. The listing describes the factory P320-XFULL package identified above; it does not include ammunition or unlisted accessories.
