SIG Sauer P320 Compact 9mm Luger, 3.9" Barrel, Black, Fixed Sights, 15+1, Three 15-Round Magazines, 2020 (RXP Optics-Ready; ROMEO1PRO Not Included)
This SIG Sauer P320 Compact is a 9mm Luger, striker-fired pistol built around the P320 modular architecture with a removable serialized FCU. It features a 3.9" barrel, fixed sights, an optics-ready slide in the factory RXP configuration (SKU 320C-9-B-RXP) with the rear sight/optic cover plate present but its two retaining screws missing, and ambidextrous slide catch levers. Manufactured in 2020 and finished in black, it comes in very good condition with an excellent bore and includes three 15-round magazines and the SIG factory hard case. Note: The factory ROMEO1PRO optic that was included with the RXP package is missing and is not included.
Notable functional details include front and rear slide serrations, a polymer grip module with molded texturing, and an integral Picatinny-style accessory rail. Takedown does not require a trigger press, and this configuration is built without a manual thumb safety. Capacity is 15+1, and it also accepts 17-round P320 magazines.

What's Included

- Three 15-round steel P320 magazines (mix of USA- and Italy-marked manufacturers)

The Compact variant balances concealability with shootability. Its 3.9" barrel and compact grip provide a familiar P320 handling profile in a smaller footprint while maintaining 15+1 capacity.
The serialized, removable FCU enables the modular P320 system, allowing the fire control unit to be moved between compatible grip modules and slide assemblies. This example retains the black polymer grip module with molded texturing for consistent control.
Front and rear cocking serrations aid slide manipulation, and fixed iron sights consist of a white-dot front blade and a square-notch rear. The slide is factory optics-ready as part of the RXP configuration, but no optic is installed or included. The rear sight/optic cover plate is present; however, the two plate-retaining screws are not included.
The integral Picatinny-style accessory rail supports common lights or lasers. This 2020-made pistol is finished in black and is made in the United States. It ships with three 15-round magazines, and it is compatible with 17-round P320 magazines as noted.
