I picked up an AREX and it is very comfortable in the hand and soft shooting. I am getting used to the trigger, it is a little sharper and angular feeling than the P365XL's flat trigger. For comparison, both pistols are fully loaded (15+1 and 12+1). Here are some photos for comparison the P365XL has the Sig Romeo0 and the AREX has the Shield SMSc and the overall weight difference is just under 3oz. The third picture doesn't show the muzzle difference very well, the AREX is approx. .25" longer than the P365XL. I was getting a lot of shadows and went with the best picture. The last two photos are the AREX and Glock 19.
