Analysis

SIG introduced the XTEN in 2022 to bring the P320’s modular X-Series features into the 10mm Auto category. The model addresses demand for a high-capacity, optics-ready 10mm that retains the interchangeable fire-control unit and ergonomic updates of the X-Series while managing the recoil of the more powerful cartridge through a heavier bull barrel and a purpose-built grip module. It expands the P320 family beyond the traditional 9mm/.40/.45 offerings and positions SIG in the growing market for full-size 10mm pistols intended for hunting, outdoor carry, and defensive use.
