The Legion RX configuration adds premium touches to the P226 platform. It features a stainless-steel slide over an aluminum-alloy frame, both finished in gray, with Legion chevrons and LEGION markings on the slide, and the SIG SAUER INC., NEWINGTON–NH–USA rollmark on the right side of the frame/dustcover. Black checkered G10 grips with Legion medallions, a checkered front strap, and an undercut trigger guard support a secure, consistent grip.
This hammer-fired, DA/SA pistol includes a decocker and a curved, short-reset trigger for rapid follow-up shots. An external spur hammer provides clear status and confident manual manipulation.
The slide is milled specifically for the ROMEO1 red dot and retains backup iron sights. The front sight is an elevated blade with a luminous TG-H3 dot, paired with a rear notch positioned behind the optic. Front and rear cocking serrations aid in slide control.
Barrel length is 4.4 inches, and capacity is 15+1 with the included Mec-Gar magazine. The dustcover features an accessory rail, and the overall package is a full-size, 9mm Legion model built in the USA.
