This SIG Sauer P320 Spectre Comp Blackout is a full-size, Custom Works build that combines an integrated single-port compensator with a tungsten-infused TXG grip module and an optics-ready slide. It features an upgraded Grayguns P320 Adjustable Straight Competition Trigger Kit (Nickel), a 21+1 capacity, and the Blackout edition’s black slide and compensator in place of earlier TiN accents, while the TXG grip module and flared magwell are the typical SIG TXG gray.

The integrated compensator is a key element of the Spectre Comp design. It is a single-port unit secured by two top screws and houses the front sight directly on the compensator. SIG reports approximately 30% recoil reduction versus the P320 XFIVE Legion, contributing to flatter tracking and faster shot-to-shot control.
The slide is optics-ready and currently configured with the optics cut open (factory cover plate not included). It features aggressive diagonal serrations plus lightening windows on the top and sides. The sight setup uses a front sight mounted in the compensator; rear sight configuration depends on the installed optics plate or optic, and sight radius varies accordingly.
The TXG tungsten-infused XSeries grip module provides added mass and stability. It includes LXG laser-engraved texture panels with SIG medallions, a pronounced beavertail, a high undercut, and a flared magwell. A full-length Picatinny/M1913 rail supports accessories without guesswork.
Barrel length is 4.6 inches and threaded 1/2x28, working in concert with the compensator. The pistol uses a striker-fired action and arrives in the Blackout edition, which substitutes black finishes for the earlier gold accents. Overall length is 8.5 inches, height 5.8 inches, width 1.6 inches, and weight 41.8 ounces. Capacity is noted as 21+1, and SIG indicates compatibility with many XFIVE Legion holsters.
This example also includes the upgraded Grayguns P320 Adjustable Straight Competition Trigger Kit (Nickel). The straight, skeletonized, adjustable design offers a refined trigger system tailored for consistent performance in a full-size P320 platform.
