The SIG SAUER P320 AXG Carry Grip Module is an OEM alloy upgrade that converts your P320 FCU into a metal-frame Carry pistol, combining the heft and durability of an aluminum frame with the comfort of interchangeable polymer grip panels. Precision-machined with deep undercuts, an extended beavertail and a medium carry circumference, the AXG module improves purchase, balance, and felt control while accepting full-size P320 slides in 9mm, .40 S& W, or .357 SIG. Built for owners who want a factory-engineered metal-frame feel without replacing their fire control unit, this module ships with a medium backstrap and is optimized for X-Series magazines — but be sure to confirm your FCU type because it will not accept Manual-Safety FCUs.
