Sig Sauer P320 XTEN 10mm 5″ | ROMEO2 | MFG# 320X5-10-BXR3-RX2

The Sig Sauer P320 XTEN is a purpose-built 10mm semi-automatic handgun with a 5″ bull barrel and X-Series ergonomics designed for controllable power and consistent performance. It ships with X-Ray3 day/night sights and an optic-ready slide that accepts compact reflex sights. The XTEN is well suited to field use and long-range handgun applications where the 10mm cartridge’s ballistic performance is desirable; pairing it with a rugged red-dot like the SIG Sauer ROMEO2 (priced under $1000) provides a durable, low-profile aiming solution that complements the pistol’s capabilities.
