The heart of this pistol is the serialized P320 fire-control unit, allowing caliber or frame changes without an additional transfer. The LXG Spectre grip module features laser-engraved texturing that enhances control and matches the compact slide length for balanced handling.
A 4.6" 1/2-28 threaded carbon-steel barrel is factory-installed and topped with a screw-on two-port compensator, reducing muzzle rise for faster follow-up shots. Shooters who prefer suppressed or standard use can remove the compensator and add a device of their choice thanks to the common thread pattern.
The optic-ready PRO footprint slide comes finished in durable Nitron and includes forward and rear cocking serrations. It accepts SIG ROMEO1Pro, Leupold DeltaPoint Pro, or RMR-pattern mini-red-dot sights without additional milling, giving the owner flexible sighting upgrades.
Suppressor-height tritium night sights provide a clear iron-sight picture above a can or optic. A flat-faced trigger delivers the consistent, crisp break that striker-fired P320s are known for, while internal striker and disconnect safeties meet duty-grade safety requirements.
With its recent 27-APR-2024 factory case label, this Spectre-series compact represents one of SIG’s latest Custom Works offerings—combining premium features, modularity, and ready-to-shoot upgrades in a single, factory-warranted package.
