The Sig Sauer P320-XTEN pistol in 10mm with a 5-inch barrel (brand part no. 320X510BXR3R2MS) brings the modular, striker-fired P320 platform to full-power 10mm, giving shooters a capable hunting and defensive round in Sig’s proven action. Sig Sauer holds a 15+1 capacity, and the optic-ready, serrated slide uses a Sig PRO RX footprint for direct red dot mounting. XRAY3 day/night sights back up the optic for reliable aiming in any light, and a manual safety adds an extra layer of control. Two 15-round magazines are included.
