SIG Sauer P320 XFive Legion 9mm with ROMEO1 PRO Red Dot, 5-Inch Bull Barrel, 21+1 Capacity
The P320 XFive Legion takes SIG Sauer’s striker-fired competition pistol and adds the Legion treatment: a tungsten-infused TXG grip module, a 5-inch stainless bull barrel, and a durable Legion Gray PVD slide with lightening cuts. This full-size 9mm ships ready for the range with a factory-installed SIG Sauer ROMEO1 PRO red-dot sight and high-capacity magazines, giving shooters a turnkey package for USPSA or IDPA Carry Optics competition.

The tungsten-infused TXG grip module adds roughly 43 oz of weight, giving the P320 XFive Legion a recoil impulse closer to that of a steel-framed pistol while retaining polymer ergonomics. The added mass helps keep the muzzle flat for faster follow-up shots.
Its 5-inch stainless bull barrel works with the skeletonized, flat-faced XFive trigger to deliver a crisp break and short reset, supporting precise, repeatable shots on target. The modular stainless-steel fire-control unit (FCU) remains the serialized component, allowing caliber or frame changes without new paperwork.
The Legion Gray PVD slide features forward and rear cocking serrations, weight-reducing lightening cuts, and is cut to accept the included ROMEO1 PRO optic. The green fiber-optic front post co-witnesses through the red dot for a rapid, daylight-bright sight picture.
Two factory SIG Sauer magazines—one extended 21-round and one flush-fit 17-round—maximize capacity options for competition or range work. An exclusive Legion program membership gives the buyer access to SIG accessories and gear not offered to non-Legion owners.
