The Sig Sauer P320 is a striker-fired 9mm pistol built on the brand's modular platform, and this compact variant pairs a medium grip module with a 3.9-inch carbon steel barrel for shooters who want duty-capable performance in a frame that works for concealed carry or range work. The optic-ready slide is machined to accept the PRO optic footprint, so you can mount a modern red dot if your mission demands it—or run it iron-sight ready right out of the box. With SIGLite night sights front and rear, you're equipped for low-light shooting without an electronics dependency.
The medium compact grip module sits between full-size and subcompact dimensions, striking a balance between control and concealability. An integrated accessory rail gives you mounting options for lights or lasers. The slide is finished in Sig's Nitron coating—a robust corrosion-resistant finish that handles duty use—and the 3.9-inch barrel is DLC-coated for added durability. The trigger is Sig's proven curved striker-fired mechanism, crisp and predictable. You get two 10-round magazines in the box, and at 26.6 ounces loaded, the gun points naturally and handles recoil management well for a mid-size 9mm.
This is a versatile platform. Whether you're building a carry gun, setting up a range trainer, or looking for a home-defense pistol that can grow with your needs via Sig's modular grip and slide ecosystem, the P320 compact gives you modern ergonomics, reliability, and adaptability. The 7.25-inch overall length and 5.25-inch height make it genuinely concealable but still large enough for a solid grip and sight radius.
