    • Protective shroud for ROMEO1PRO (installed)

    Built by SIG Sauer Custom Works, the Spectre Tacops RXP pairs the P320's modular FCU architecture with the Spectre slide styling and practical upgrades. The result is a factory-configured package that brings together performance features and Custom Works fit and finish. The case label confirms the model code P320V005-RXP.

    The 4.6 inch extended barrel is threaded 1/2x28 and ships with a thread protector. The slide wears a coyote tan finish with Spectre lightening cuts plus forward and rear serrations, creating a controlled gripping surface and reducing visual mass. The overall two-tone coyote tan/black finish offers a purposeful look consistent with the Spectre series.

    A factory-installed SIG Sauer ROMEO1PRO red dot and its protective shroud come mounted and ready. Suppressor-height co-witness sights back up the optic, with an X-RAY3 tall front sight featuring a green dot for fast indexing.

    Capacity is 21+1 in 9mm Luger, and this pistol includes four 21-round steel magazines. The XSeries LXG laser-engraved grip, flared magwell, and extended beavertail aid control and reloads, while the reversible magazine release and ambidextrous slide catches support varied user setups.

    The black polymer frame integrates a Picatinny-type accessory rail for lights or other compatible accessories. The striker-fired action and overall configuration reflect the Spectre Tacops RXP focus on modern ergonomics and sighting systems.
