The latest addition to the Sig P320 family brings all of the features of the XSeries into a carry-style handgun in 10mm for shooters and hunters looking for performance to the power of 10. The P320-XTEN comes standard with a 5″ bull barrel, X-RAY3 day/night sights, and an XSeries optic-ready slide with front and rear serrations. For those looking for even more precision, every P320-XTEN is optic-ready and compatible with the Sig Sauer ROMEO2 reflex optic which is designed to withstand the abuse the 10mm cartridge delivers. To reduce the recoil, a completely redesigned XSeries polymer grip module provides a strong purchase and stippled finish and makes shooting comfortable for any type of round. Each P320-XTEN comes standard with two 15-rd magazines.
Please Note: The P320-XTEN is not compatible with 9/357/40 caliber parts and accessories. Only .45 and 10mm parts and accessories are compatible with this model.
