Sig Sauer P320 AXG Legion Comp 9mm 3.9" 21rd Romeo-X Pistol

The P320 AXG Legion Comp puts Sig's fire control unit into an all metal AXG grip module and cuts a two port expansion chamber into the top of the slide. The metal module adds weight down low in the hand, the ports vent gas up top, and between the two the front sight barely moves under recoil. Hogue custom G10 grip panels and a magwell are already fitted, and the flat skeletonized trigger is standard across the Legion line.

A Romeo-X Pro optic sits on the X series slide. Magazines hold 21 rounds, which is what the full size AXG module was built around, and the 3.9" barrel keeps the slide short enough that the pistol still handles like a duty gun instead of a competition rig. Legion has always been Sig's answer to shooters who would rather the factory do the work than pay a custom shop to do it later: better sights, better grips, a better trigger, an all metal frame, and a finish that identifies the gun across a range. This version adds the comp, and a compensated 9mm this heavy barely moves.
