The Spectre Comp Blackout configuration integrates a single‑port compensator into the slide, and the front sight is dovetailed into the comp. SIG reports roughly 30% recoil reduction versus standard P320s, pairing control with the included X‑RAY3 day/night front sight for clear sighting in varied light.
The optics‑ready slide features aggressive front and rear serrations and lightening windows, finished in Cerakote Elite Blackout with an all‑black barrel and flat, skeletonized trigger. A SIG Sauer ROMEO1 Pro red dot comes installed, and a cover plate is included for use without an optic.
The TXG tungsten‑infused polymer XSeries grip module with LXG laser‑engraved texture and a detachable flared magwell offers a planted feel. Controls include a reversible magazine release, and the frame carries a Picatinny/M1913 accessory rail for lights or other mission‑critical additions.
