The Sig Sauer P320-XTEN pistol in 10mm with a SIG-LOC optic mounting system (brand part no. 320X5-10-BXR3-RXSL) delivers a full-power 10mm striker-fired pistol built for hunting, defense, and outdoor carry. Sig Sauer builds the pistol with a 5-inch barrel and a 15+1 capacity, and night sights support reliable aiming in low light. The SIG-LOC optic mounting system secures a red dot directly to the pistol’s frame rather than the slide, keeping the optic stationary during the slide’s reciprocating cycle. Among 10mm semi-auto handguns, this P320-XTEN configuration favors shooters who want full-power capability with a stable, frame-mounted optic option.
