It is my understanding (theoretical at this point as I have handled neither but have several p320's on order) that felt recoil would be more in the AXG as it is an alloy, and therefore would not offer the same degree of dampening of either the tungsten polymer frame of the Legion Carry, or that of a heavier all-steel hammer-fired pistol. However, the AXG looks a lot cooler. Form vs function. If I hadn't ordered a p226 Legion as well (which has similar grip appearance), I'd go with the AXG for the looks. If you want a purely functional tool, I'd say the Legion Carry would handle a bit better than the AXG. If I had to have only one Sig for life, I'd go with the p226 SAO RXP Legion. Of course, if it has to be striker fire, with the p320 you can always just buy one, and throw the FCU in the grip module of the other down the road. The AXG grip module is a little harder to come by and looks better, so I would probably say AXG now, and tungsten polymer XCarry grip module (or XFive conversion kit) down the road once the bank account has recovered.
