SIG P320 Introduction

The SIG P320 is a revolutionary semi-automatic pistol developed by Swiss/German firearms manufacturer SIG Sauer, featuring a groundbreaking fully modular design. Unlike traditional pistols, the P320 uses an innovative “Fire Control Unit” (FCU) as the legally defined “firearm,” allowing users to easily swap grips, slides, barrels, and other components, transforming one pistol into multiple configurations.
