Special Features
The MACH3D compensator is 3D-manufactured using advanced gas-flow engineering to redirect propellant gases and significantly reduce muzzle rise, allowing faster and more consistent follow-up shots without mechanical compromise
The SIG-LOC PRO optic footprint on the slide provides a secure, stable mounting platform for full-size red dot sights with no adapter required, keeping the optic low and co-witnessable
High-polish titanium nitride finish on the controls and magwell delivers superior corrosion resistance and a distinctive visual contrast that identifies this pistol as part of SIG’s Spectre Custom Works family
Custom brass LOK grip panels with GridLOK texture add meaningful mass to the grip frame, improving balance and providing a secure, tactile surface that does not loosen over time
P320-compatible steel magazines make replacement and sourcing straightforward, and the 23-round capacity provides a meaningful advantage in competitive and high-round-count range applications
The flat skeletonized trigger is engineered for a clean, consistent break with minimal overtravel, supporting repeatable accuracy during extended firing strings
Full-length dust cover and integrated Picatinny rail allow direct mounting of weapon lights or lasers without adapters
