I have three of the Blackhawk Discreet Weapons Cases of my own - they are not designed for two firearms. There are multiple rows of PALS webbing inside, and two hook and loop straps that can be repositioned to accommodate the design of your firearm. As well, there is a very large zippered pouch on the outside that holds lots of gear, any pouch or accessory with a hook backing is easy to position.
My oldest Discreet case is pushing 15 years, I'm very satisfied with mine.
