We’ll cover everything about the P320 in our review…from features to accuracy, reliability, ergonomics, upgrades, and pricing. By the end you’ll know if the P320 is right for you or if the Army is stuck with a dud.
When I look at a new gun, I like to spot the one big thing that’s different. I always hope there is something noteworthy and unique, or else it would be like plenty of other guns, and that would be a boring review, wouldn’t it? With the Sig Sauer P320, finding that one big area of differentiation was easy: its modularity. Well, technically speaking, I suppose there are three big areas because that modularity concept applies to fit, size, and caliber.
There are a lot of truly different features on the P320. The most outwardly unique aspect of this pistol is the grip frame, which we’ve come to accept as the handgun’s core. On the P320, it is merely a hollow shell of molded polymer. All of the internal working parts—what SIG Sauer calls the “fire-control assembly”—are housed in a single, serialized stainless steel unit that detaches from the frame in seconds. This allows the user to change the entire grip frame to suit his or her individual body size or unique mission requirements.
