If you aren't already aware of it, you might want to take a look at the J107 "tactical" model.
The tactical model uses solid cordura instead of mesh for the main compartment material, and you don't have the camo options, but otherwise the same pack as the hunting version, but with a wide scabbard.
I'm quite fond of mine. Seen below stuffed to 50lbs with my wife's old magazines for conditioning
Note: That big top part can be removed (/used as a fanny pack with the belt portion if you want) to cut down on the bulk of the main back.
