The Legion-series P365-AXG combines a micro-size 9mm format with a robust AXG aluminum grip module dressed in Legion chevron G10 panels. A flared, screw-retained magwell supports quick magazine changes while maintaining the compact footprint buyers expect from the P365 family.
Its stainless-steel slide wears a Legion Gray Cerakote finish and features front and rear cocking serrations. An integrated two-port expansion-chamber compensator is machined into the slide assembly, with the front sight set back behind the comp for a clean sight picture and reduced muzzle movement.
The pistol is optics-ready with an RMSc/Shield footprint and comes equipped with SIG XRAY3 day/night sights (green-outline tritium front, tritium square-notch rear). The flat-faced trigger and reversible magazine release provide a modern, user-focused control layout, and there is no external manual safety.
Capacity is listed at 21+1 and this package includes one 21-round and three 17-round steel double-stack P365 magazines (extended-length and standard-length types). Dimensions remain carry-friendly at an overall length of 6.6 in, width of 1.4 in, and a weight of 26 oz with magazine. The 3-slot 1913 Picatinny rail accommodates compatible accessories.
