SIG Sauer P320 Custom Works Spectre Comp Blackout 9mm, Full-Size, 4.6 in 1/2x28 Barrel, Integrated Comp, TXG Grip, ROMEO1 Pro, 3x 21-Rd Mags
This Custom Works Spectre Comp Blackout P320 stands out with its integrated single-port compensator, tungsten‑infused TXG grip module, and an installed SIG Sauer ROMEO1 Pro red dot. It is a full-size 9mm with a 4.6 in threaded barrel, 21+1 capacity, and a feature-rich slide, delivered in excellent condition with three 21-round magazines.
The slide combines forward and rear serrations, lightening windows, an optics cut, and a proprietary single-port compensator secured by twin top screws. The front sight is mounted on the compensator and uses a green dot; iron-sight radius varies by configuration. A flat, skeletonized trigger and striker-fired action provide a consistent trigger feel.
The TXG tungsten‑infused XSeries grip module with LXG laser‑stippled texture and a flared magwell adds mass and grip traction. Overall dimensions are 8.5 in long, 5.8 in high, and 1.6 in wide, with a weight of 41.8 oz. The frame is gray TXG tungsten‑infused polymer; the slide is finished in black.
This Spectre Comp uses the P320 modular FCU with a serial window and includes bilateral slide catch levers, an undercut trigger guard, and a 1913 Picatinny accessory rail. Capacity is 21+1, and it ships with three extended 21-round steel magazines.
The barrel is threaded 1/2x28 and paired with SIG’s integrated compensator assembly with the front sight on the comp. SIG cites up to ~30% recoil reduction versus the P320 XFive Legion and compatibility with XFive Legion holsters. Country of origin is USA.
