Owners of the P320 XTen gravitate toward it as a full-power 10mm option built on the familiar P320 platform. The 5-inch barrel and 15-round capacity are frequently cited as the standout combination for those who want a capable field or duty pistol in 10mm. The modular P320 chassis is seen as a bonus for those already in the Sig ecosystem.

The XRAY-3 sights get positive marks out of the box, and the optic-ready cut satisfies those who want to mount a red dot without additional milling. The manual safety divides opinion: some appreciate it as an added option, while others find it unnecessary on a striker-fired platform.

Recoil with full-power 10mm loads is noticeable and some find it fatiguing during long range sessions, though the full-size frame helps manage it better than compact alternatives. Pricing sits at the higher end of the 10mm pistol segment, which most accept given the P320 build quality, though a few question the value over comparable options.
