    • Case

    The AXG metal grip module provides a rigid alloy frame with an extended beavertail, high undercut, checkered front strap, and a textured backstrap insert. A flared alloy magwell is installed for fast magazine changes. The frame and slide wear a uniform Legion Gray finish.

    The full-length slide houses a compact 3.9 in barrel and incorporates a slide-integrated expansion chamber with two top ports. Front and rear slide serrations offer positive traction. The front sight is mounted on the comp block, and the slide includes an optic cut.

    Controls are set up for versatility: an ambidextrous slide catch and a reversible magazine release. The trigger is the X-Series flat, skeletonized design. A 1913/Picatinny accessory rail on the dustcover is integral to the frame.

    The pistol uses iron sights with a dovetailed rear notch and a dovetailed front blade featuring a green ring. Capacity is 21+1 with the included factory 21-round steel magazine. The FCU serial number visible in the window matches the supplied number. Country of origin is the USA.
