The slide includes forward and rear serrations, a top window cut, and an external extractor. A full-length dustcover with a 1913 accessory rail adds mounting space, while the stainless-steel construction wears a Nitron black finish for a uniform, duty-style appearance. SIG XRAY3 co-witnessing sights remain in place with the optic installed, with a green front sight for quick sight reference.
The 4.0 in bull barrel is paired with a factory MACH3D 3D-printed single top-port compensator that is pinned and locked to the slide assembly. The installed ROMEO-X uses a ring-dot reticle and mounts via the SIG-LOC PRO optic interface, offering a sealed-emitter design suited to this package.
Capacity is 21+1 using SIG P320-pattern double-column magazines, and this pistol includes three 21-round steel magazines. The aluminum-alloy grip module features removable alloy grip panels, frontstrap and backstrap checkering, and a flared magwell to speed reloads.
Controls are set up for confident operation: single-action only with a flat-faced trigger, reversible magazine release, ambidextrous thumb safety, beavertail grip safety, and a skeletonized hammer.
