SIG Sauer P320 Spectre Comp Custom Works 9mm, Full-Size, 4.6 in Threaded Barrel with Factory Single-Port Comp, TXG Grip, Optics-Cut Slide, 2x 21-Round Mags
The SIG Sauer P320 Spectre Comp from SIG Custom Works is a factory-compensated, full-size 9mm built with premium features throughout. It combines a 4.6 in threaded, TiN-coated barrel with a single-port compensator, a windowed optics-cut slide, and the tungsten‑infused TXG XSeries grip module. This example includes two 21-round steel magazines, the original factory box with matching serial-number label, the P320/P320 XSeries manual, a gun lock, and an additional FDE P320 grip module in retail packaging.
The slide is optics-cut and features lightening windows plus front and rear serrations for confident manipulation. The rear sight is mounted to the optics cover plate, while a green dot front sight rides on the compensator, maintaining a consistent sight picture with the comp installed. The slide wears a black finish that contrasts with the gold TiN barrel and flat, skeletonized trigger.
The 4.6 in barrel is threaded 1/2-28 and capped by a factory single-port compensator retained by two top screws. The compensator integrates the front sight and is designed specifically for this Spectre Comp configuration. The TiN coating on the barrel and trigger provides the distinctive gold appearance noted on Custom Works builds.
The full-size TXG XSeries grip module is polymer infused with tungsten for added mass, featuring LXG laser-engraved texturing and a flared magwell. A full-length M1913 accessory rail is molded into the frame. Dimensions are approximately 8.5 in overall length, 5.8 in height, and 1.6 in width; listed weight is 41.8 oz.
Capacity is 21+1 with the included extended steel magazines marked "MADE IN ITALY." Markings on the pistol include "CUSTOM WORKS," "SIG SAUER P320," and "NEWINGTON, NH, USA," reflecting its U.S. manufacture.
