The AXG Legion pairs a full-size AXG aluminum grip module with a removable flared magwell and extended beavertail, delivering the Legion series’ distinctive look and handling. Both the frame and stainless steel slide wear the Legion Gray finish, and the flat, skeletonized trigger complements the striker-fired action.
The slide features aggressive front and rear serrations, an optics cut with a removable cover plate, and an integrated two-port expansion chamber. The optics interface is compatible with SIG ROMEO1Pro and ROMEO2 footprints.
SIG X-RAY3 day/night three-dot iron sights come installed. The front sight uses a bright green dot marked 1G-H3, while the rear sight houses two tritium vials. A full-length dust cover with a three-slot Picatinny rail provides room for rail-mounted accessories. This pistol has no manual safety per factory configuration.

Capacity is 21+1 when using the included extended magazines. The extended magazines are marked "MADE IN ITALY," and the flush-length 17-round magazine is marked "MADE IN USA." Made in the United States.
