Balancing concealability, firepower, and controllability is the central challenge for anyone shopping for a personal-defense pistol. A compact, modern striker-fired design that preserves capacity while delivering potent terminal performance can be the difference between a defensive advantage and a compromise.

SIG SAUER P320 XTEN is built expressly for that balance: a compact carry-oriented pistol chambered in 10mm with a 3.8″ barrel, striker-fired operation, and a notable 15-round magazine capacity. This configuration gives users a compact package without sacrificing rounds or stopping power.

Design and Ergonomics

The SIG SAUER P320 XTEN’s 3.8″ barrel gives a compact footprint for concealed carry while preserving sight radius and velocity compared with shorter-barrel compact pistols. As a striker-fired platform it offers a consistent trigger feel and simplified controls for quick familiarization. The 15-round capacity in a 10mm compact package is an outlier in its class — putting more defensive rounds on tap without dramatically increasing grip bulk.

Performance and the 10mm Advantage

Chambering the XTEN in 10mm delivers substantial ballistic performance versus typical service calibers. For personal defense the 10mm provides superior penetration and energy transfer, which can translate to improved terminal effectiveness at typical encounter distances. Shooters should pair the pistol with loads they’ve tested for reliable function and manageable recoil, and take advantage of the pistol’s ergonomics to tame follow-up shots.

Managing Recoil and Capacity

Though 10mm produces stout recoil, the XTEN’s compact slide-mass and ergonomics help mitigate muzzle rise. Paired with the 15-round magazine capacity, the platform supports realistic defensive reload strategies and extended practice sessions without constant magazine changes.
