I a a big 365 fan boy. I actually shoot the original small sized the best, then my Macro comp just a little worst and the XL the worst by a slight amount. It is all going to depend on your hands and what you like. I really like mine!!!!

I had a P365 when they first came out but found the grip too small so sold it off. Picked up another one later once the Wilson Combat grip modules were out for it and with one of those it's a great fit.

The P365, P365XL, P365 XMACRO with a Holosun is the best carry options on the planet earth. If anyone disagrees they are just ignorant.
