The P320 Full-Size configuration pairs a 4.7 in barrel with a 17+1 capacity, delivering the long sight radius and controllability many shooters prefer in a duty-length slide and grip. The serialized, stainless-steel FCU chassis provides the P320’s modular foundation inside the polymer grip module.
Controls are well-sorted, with ambidextrous slide catch levers and a left-side magazine release. The curved trigger and a takedown procedure that does not require a trigger press support confident handling and straightforward maintenance.
Sight alignment is fast and clear through fixed, dovetailed 3-dot sights, aided by a 6.6 in sight radius. The slide includes front and rear serrations for positive manipulation and is an optics-ready configuration with a factory cover plate.
An integral multi-slot Picatinny/M1913 accessory rail is molded into the grip module for mounting as needed. Overall dimensions are 8.0 in in length, 5.5 in in height, and 1.3 in in width, with a weight of 29.5 oz with magazine. This P320 is made in the USA and includes two 17-round steel magazines with orange followers.
