The Sig Sauer P320 10mm X-Series is a full-featured duty and hunting pistol built on the modular X-Series platform and chambered in the hard-hitting 10mm cartridge. If you're serious about 10mm performance—whether for hunting, defense, or precision shooting—this optic-ready platform gives you the accuracy and ergonomics of Sig's modern X lineup in a caliber known for real stopping power and range capability.
What sets the P320 X-Series 10mm apart is the combination of a 5-inch bull barrel, optic-ready slide, and a completely redesigned grip module engineered specifically for 10mm recoil management. The stippled, textured grip provides a secure hold through heavy rounds, while the new X polymer module absorbs and manages the cartridge's signature kick without sacrificing control. The flat X trigger breaks clean at 90 degrees, supporting the precision shooting that 10mm demands at distance.
The slide is milled and ready for mounting red-dot optics—compatible with the Sig Romeo2 and Trijicon RMR (with sealing plate)—so you can mount your choice of modern reflex sight. Iron backup is handled by Xray3 day/night sights, giving you reliable aiming solutions in any light. The front and rear serrations aid in manipulation and aesthetics. You get two 10-round steel magazines in the box, so you're ready to load up and shoot.
This is a serious tool for hunters and shooters who understand 10mm's ballistics advantage and want a modern platform to deliver it accurately downrange.
