i carry a 45 all the time, its either my duty colt full size which i carry off duty most of the time, or my glock 30 45 that i carry in a chest holster when i have to waer a tuck in shirt.
its not that don't like 40, its a great round, i just prefer the 45. and my glock 30 is perfect for deep carry. everywhere else though its my colt that i also carry on duty!
