The Compact Full-Length Slide configuration places the full-size 4.7 in slide and barrel on a compact grip module. This factory setup (320C-9-FLS) offers the longer slide format in a compact-profile frame, and it retains the modular P320 design with a removable, serialized fire control unit.
Construction is centered on a stainless slide and stainless barrel with a Nitron finish over both. The slide carries front and rear serrations for easy manipulation. Sighting is via fixed 3-dot contrast units in dovetails: a white-dot front and two-dot rear.
This pistol is striker-fired with a curved trigger and a reversible magazine release. It has no external thumb safety and includes the mechanical disconnector and updated fire-control components associated with the post–August 2017 production upgrade. It is labeled Made in United States, and the factory case label is dated Nov 29, 2017.
The frame provides a full-length M1913 accessory rail with four slots for mounting compatible lights or accessories. Capacity is 15+1 in 9mm Luger, and this example ships with two 15-round steel magazines, the factory hard case, the P320 operator's manual, and a SIG polymer paddle holster.
