The 365 has it's advantages and I personally feel you should have both but definitely try one out first. When it absolutely, positively has to be concealed without printing, I carry a Mustang the same size as the 938. When you try out the 365 (you should be able to rent one at many indoor ranges), if you like it you have to ask yourself whether the slightly larger size will mean it gets left home.
Now you see the advantages of having both. If the answer is yes, just swap out the 365 for the 938 on the way out the door.
