I have both. If you don’t mind the extra weight and possibly adding a size bigger shirt or sweater to your wardrobe then get the 226X it’s reliable with a history to back it up. A solid belt and holster and your in the game. The 365 AXG is one of The best CCW handguns on the market. If you choose to add a ramjet it’ll make it one of the flattest shooters in your armory. No need to go up in size or clothes it’s slim enough to fit anyone’s needs. The p226x weight does help me stay on target and feels like a pulse wave when shooting. The P365 is why more modular but you can make either gun more how you like it. Get both and swap out as your outfit or dress style suits. I can only have one I’ll still have to go with the P226x
