I have owned both the Fatboy and the Jumbo Fatboy, if you intend to carry a medium sized weapon, or should I say, you are not intending to carry a small weapon (ie: J frame or small auto), I strongly recommend you get the Jumbo Fatboy. It's quite tight getting your hand in the zippered pocket of the Fatboy and the Fatboy's pocket was too small for my G-23. The Jumbo Fatboy was much better in that regard.
