The Spectre Comp Blackout configuration delivers a factory-compensated P320 with a separate compensator block secured by two top screws. The front sight is mounted on the compensator, giving a consistent sight picture relative to the compensator assembly.
Its stainless slide wears a Blackout Cerakote Elite finish and includes front and rear serrations and lightening windows. The combination offers a distinctive look with practical handling surfaces.
The TXG tungsten-infused grip module with LXG laser-engraved texture provides a stable, tactile hold and includes a detachable flared magwell. The frame is finished in black and retains the P320 modular ergonomics.
Controls are set up for broad usability with an ambidextrous slide catch and a reversible magazine release. X-RAY3 day/night iron sights pair a green-dot front (on the compensator) with a black rear notch. An accessory rail on the dust cover accommodates the included FOXTROT2R light or other rail-mounted accessories.
