After having a Jumbo........you may want to consider the Colossus. A little bit bigger and better suited.
The jumbo just isn't quite wide enough. The Colossus is only slightly larger.
Would the jumbo fit an open gun in the CCW compartment? That's the only concern I have. I am planning on putting my ammo in a 6"x6" pouch that would attach outside the jumbo versipack. So, that would leave me more room for other crap I need to put inside the main compartment. Thanks in advance.
