The Spectre Comp integrates a single-port compensator at the front of the slide, with the green-dot front sight mounted directly on the comp to maintain sight tracking. SIG X-RAY3 day/night sights are standard, and the slide features an optics-ready cut with a rear cover plate installed, plus elongated top and side ports to shed weight.
A 4.6 in threaded barrel (1/2-28) wears a gold TiN finish, matched by the flat, skeletonized TiN trigger. The pistol uses the modular P320 fire control unit architecture, with a stainless steel receiver and DLC/Cerakote slide finish. A 5-slot Picatinny accessory rail is molded into the polymer dust cover.
The full-size XSeries grip module adds LXG laser-engraved texture for traction and a flared magwell for fast magazine changes. Capacity is 21+1, and two extended steel magazines are included. The setup is generally compatible with XFIVE Legion holsters.
Overall length is about 8.5 in with a sight radius of approximately 6.5 in and an unloaded weight of about 41.8 oz. Markings include a frame rollmark of NEWINGTON, NH, USA, slide SIG roundel with CUSTOM WORKS, and right-side SIG SAUER P320. Made in the USA; Custom Works series with Spectre Comp configuration. SIG reports approximately 30% recoil reduction versus the P320 XFIVE Legion.
