The Sig Sauer P320 9mm pistol in this two-tone FDE configuration is a modern, modular fighting gun built for shooters who want customization without compromise. This particular model pairs a 4.6-inch threaded barrel with an optic-ready slide engraved by Sig's Custom Works, giving you a platform ready for suppressors, red dots, and serious duty or competition work. The FDE (flat dark earth) anodized grip module and Hogue G10 Coyote Tan grips deliver both durability and a professional grip profile, while the stainless steel frame and Nitron-finished slide handle the recoil and rounds without hesitation.
What sets this P320 apart is the complete feature package from the factory. You get suppressor-height XRay3 day/night sights for low-light work, a flat skeleton trigger from Sig's X-Series line that breaks clean and predictable, and three 21-round steel magazines—that's 63 rounds of capacity out of the box. At 8.1 inches overall length and 34.7 ounces loaded, it sits right in the sweet spot for concealed carry or duty use without feeling unwieldy on the range.
The P320 platform is proven across military and law enforcement worldwide, and Sig's modular design means you can swap grip modules, barrels, and slides to tune this gun to your exact needs down the road. Whether you're training for competition, running it as a duty gun, or building a suppressed bedside rig, this configuration gives you serious versatility and factory-backed quality right out of the box.

Yes. The 4.6-inch barrel is threaded 1/2x28, the standard thread pattern for 9mm suppressors. The suppressor-height sights also sit above a can's profile, so you'll maintain your sight picture when running suppressed.
Yes. The slide is engraved by Sig's Custom Works and features optic-ready mounting provisions, so you can mount a red dot sight directly to the slide.
Three 21-round steel magazines are included.
The P320 uses a modular grip module that houses the fire control group. You can swap the grip module, barrel, and slide to change caliber, barrel length, or ergonomics—essentially building a new gun without buying a new gun. It's a huge advantage if you want to adapt one platform for multiple roles.
