The combination of the SIG P320 with the parts and work made by Wilson Combat gunsmiths received the WCP320 name. The pistol is made on the basis of unfinished slides for the P320 supplied by SIG along with barrels and trigger modules. Wilson Combat finishes the slides, mounts the sights, improves the workings of the trigger and places the whole in its own polymer grip with improved ergonomics. It is interesting to see a Carry's grip combined with a full-size slide, which reveals the bottom of the slide like in, e.g. 1911 pistols. The whole costs 1,200 USD.
The buyer receives a pistol with improved front, rear and side incisions on the slide (X-Tac P320) for easier control if the chamber is loaded. Vicker’s Tactical Battlesights, a black U-shaped rear sight and a front sight with a fiber optic insert are mounted on the slide. It and the barrel are finished with DLC (Diamond Like Coating) coating in black.
The grip is in the Carry size (shortened front part and full-size grip) is available in black and tan, depending on the customer's taste. The trigger is flat, the same as usually found in the P320 X series. The trigger guard is undercut at the grip and rounded, and the grip's nub is elongated. The sides were textured with a laser, and the front and back of the grip were equipped with a skateboard texture. The last improvement is the widened magazine well. The manipulators are the same as the factory fitted, and a lack of a mount for a miniature collimator on the slide is puzzling. The set includes two magazines 9x19 mm holding 17 rounds.

It is worth noting that Wilson Combat Carry size grip modules are also available separately, in which the owner of the factory made P320 can mount his trigger module and the slide. They cost only 65 USD, which is a fantastic choice considering that it is a price lower than ordering a stippling service. They are compatible with both the full-size P320 slide and the compact version. Probably this is why they are currently sold out.
