I've got one. I really like it, I just wish it wasn't Blackhawk. It holds the two long guns, plus has 2 pockets: 1 padded and zipped, the other unpadded and large velcro flap. The zippered pocket holds 2 triangular padded gun rugs easily, and the flap pocket is big enough for 3 30 round mags, 2 boxes of 12GA shells, 4 boxes of .45, eyes, and ears. I definately DO NOT like the shoulder strap. Actually, the strap itself is fine, it's the little clips on the end. They don't swivel and they're cheaply made. I need to get down to the sporting goods store and find a heavy duty duffle bag strap with good clips. The bag is large enough to hold pretty much anything except for some long-barrelled bolt actions I've got.
Let me just say this: I don't like Blackhawk, but I can't find anyone else that makes a double long gun discreet bag. I know you're looking for a bag that holds 2 long guns, but if you decided you only wanted 1 gun, the Eagle Industries Soft-Hard Discreet Case is the best.
