I carry a 365XL with the 365 grip module with the flush 10rd magazine. This allows for a pretty good grip with my hand and much better concealment than the longer frame on the XL. During winter when I usually have a jacket I will throw a 12rd mag in there. I honestly don't care at all about aesthetics when it comes to my carry guns, the available options provided by using the normal 365 grip module is worth it for me over the "cleaner" look of the XL grip. I also carry a small sling bag with me everywhere I go and have a 15 rd mag in there. If it comes down to needing more than 11/13 rds in a real world scenario the last thing I am going to be concerned with is how goofy my pistol looks with the 15rd extendo mag sticking out of the grip.
