The X-Series full-size grip module and two-tone setup give this pistol a purposeful look and feel, with a bronze slide over a black polymer frame. The slide is optic-cut and features both lightening cuts and a top window to reduce mass and aid tracking.
The 5.5 inch stainless steel barrel is threaded and spiral fluted, and it wears a knurled thread protector. The configuration is competition-leaning, with a flat-faced, skeletonized trigger for a consistent break and an extended thumb-rest style takedown lever.
Sighting is straightforward with a green fiber-optic front and a black rear iron sight. A 4-slot M1913 accessory rail on the dustcover supports rail-mounted lights or similar equipment.
As a modular P320, it uses a serialized, removable FCU and an X-Series grip module with enhanced texture. Capacity is 21+1 with the extended magazine, and a standard-length 17-round magazine is also included.
