SIG Sauer P320 XFull 9mm 4.7in | 320XF-9-BXR3P-R2-10

The SIG Sauer P320 XFull is a full-size 9mm X-Series pistol built around the modular P320 chassis. It features an optic-ready slide with an XRAY3 day/night sighting system and an XSeries grip module designed for a high grip and improved recoil control. An optic such as the SIG Sauer Romeo1PRO pairs directly with the XFull’s rear sight plate and is a practical choice for shooters seeking a robust red-dot solution under $1000.

Intended applications for this platform include precision range training and competition or service-style carry and duty use where full-size ergonomics and sight radius are valued.
