Description
The P320 X-Full is Sig Sauer’s full-size competition-oriented variant of the P320 platform, and this California-compliant configuration makes it available to shooters in that state without sacrificing the core engineering that defines the X-Series. It suits the range shooter or competitor who wants a factory pistol built around a longer sight radius and a grip that fills the hand without modification.
The striker-fired action uses the same serialized fire control unit that made the P320 adaptable across frame sizes — the trigger group is a self-contained chassis that sits inside the grip module, which means the functional lockwork is consistent regardless of which X-Series variant you run. The manual safety on this model gives shooters who prefer a mechanical disconnection between carry and ready-to-fire a concrete option without requiring any aftermarket work.
X-Ray 3 sights use a tritium front insert surrounded by a photoluminescent ring, which means the front sight remains visible under both low-light and bright daylight conditions — the ring charges in ambient light and glows without requiring batteries. The rear sight is notched to frame the front post quickly, keeping the sight picture clean during fast target transitions.
This pistol ships with two 10-round steel magazines. The frame and slide are built from polymer and stainless steel respectively, keeping the package durable without adding unnecessary weight to a full-size platform.
