If you've spent time with the SIG P320, you know it’s more than just a sidearm. In its decade on the market, it’s evolved from a fresh newcomer to a trusted tool in military, law enforcement, competition, and personal defense. But with its broad aftermarket, deciding on the right upgrades can feel like you’re in a never-ending parts catalog. Let’s break down some of the best options to transform your P320 into a customized weapon that feels like an extension of your own hand.

Crafting Your Grip: Where Comfort and Control Collide

When it comes to upgrading the P320, grips are a solid starting point. While SIG’s factory grips are no slouch, the options out there today range from performance-oriented to downright luxurious. Here’s what stands out:

Wilson Combat Grips

Wilson Combat’s P320 grip modules are as versatile as the pistol itself. These grips are ideal for a wide range of users, from those looking to enhance their everyday carry (EDC) setup to competitors seeking that extra edge. With options in colors like Coyote, Gray, and classic Black, plus sizing from full-size down to compact, Wilson Combat offers a simple yet effective way to elevate your P320. Installation is straightforward, and the recontoured design feels incredibly natural, making it easier to reach controls without losing your grip.im

Brouwer Solutions M1811

For the nostalgic shooters among us, Brouwer’s M1811 delivers. Modeled to mimic the 1911 grip, this one brings a bit of “retro cool” to your P320 while still maintaining functionality. The textured side panels feel comfortable, even for concealed carry, while the front and backstraps give your hand the needed traction during high-energy firing. This grip isn’t just about aesthetics—it feels great to hold, making it ideal for anyone looking to combine old-school charm with modern performance.

Icarus Precision A.C.E. 320 SOCOM Carry

If quality and refinement are what you’re after, the A.C.E. 320 SOCOM Carry might just be the ultimate choice. With its lightweight aluminum frame and carefully contoured grip, it’s designed for shooters who prioritize precision and style. The SOCOM Carry is a fantastic addition if you’re serious about upping your game, offering that little extra weight for improved balance without overloading your holster. The downside? It’s pricey, and the metal can get cold to the touch, but it’s hard to match the performance—and it’s my Editor’s Pick.

Grayguns Grips

Finally, the Grayguns grips might look unassuming at first, but these laser-sculpted modules are deceptively functional. Though they don’t offer the flashiest design, they provide reliable grip without excess aggression, a surprising blend of function and comfort that impresses when it matters most: on the range.



Whether you're a competitive shooter or someone looking for a trustworthy EDC setup, the P320 can be your perfect partner with the right upgrades. From classic grip textures to high-tech aluminum frames, there’s no shortage of ways to make this pistol feel like it was made just for you. Whatever path you take, remember that each piece should work in harmony with the rest of your setup. With the right components, the P320 will feel more than just reliable—it will feel like it was made just for you.
