What’s Included
- Sig Sauer P320 Spectre Comp Custom Works 9 mm pistol
- 2 × 21-round steel magazines with extended polymer base pads marked “MADE IN ITALY”
The slide-integrated compensator pairs with forward lightening ports to vent gas upward, cutting muzzle rise and keeping sights flat for faster follow-up shots. This compensator is machined directly into the slide, so it stays locked in place and functions with standard 9 mm pressure loads.
A TXG tungsten-infused polymer grip module adds substantial weight without sacrificing ergonomics. The added mass, combined with the compensator, noticeably reduces felt recoil and muzzle flip while preserving the familiar P320 grip geometry.
The Custom Works flat-faced, skeletonized trigger delivers a clean break and short reset, enhancing control during rapid strings. A reversible magazine release supports left- or right-hand operation.
Sig’s modular serialized fire-control unit lets owners swap calibers, slides, and grip modules as needs evolve, giving this pistol long-term adaptability. The slide is ready to accept popular micro-red-dot footprints, and the five-slot M1913 rail accommodates weapon lights or lasers.
