I am more of a .45 and 9mm guy, but I do have a .380 and a .40. ETA: It is the Glock 26 and my G22 that are missing from the photo below.... oops.
ETA2: With the latest advances in hollow point technology, the 9mm isn't the same weak *** round that it was 10 years ago. The only place is makes a difference is for military applications where the US only allows ball ammunition, or non-expanding rounds, per the Geneva convention. If you were carrying a mag full of full metal jackets, I would recommend going for the biggest projectile you can comfortably shoot out of a handgun!
