I have two 5.11 Moab bags, one a little more covert (civilian). The problem I've found with them is that they have a single shoulder strap. I guess the idea is to carry it in a cross-body configuration. The issue is that they both balance poorly and try to hang away from my back, awkwardly pulling away from my body. One even has a second clumsy horizontal strap, to correct this I suppose. Somehow I thought I could configure the shoulder strap to make the bag hang at my side, like a messenger bag. Because of the way the single strap is sewn into the middle of the bag, this is impossible. Don't even ask why I bought the second one! Access to the bag is awkward and someone could easily empty it for you from behind in a crowded urban setting. To make matters worse, I ordered a separate pistol module that attaches on the outside. Found out it only has a velcro attachment, no buckles or a more secure way to secure it. It could easily fall off. Although extremely well made and sturdy, I feel the design is flawed, which I don't understand considering the hype about being tactical tested. My advice: buy a messenger type bag that you can sling from one shoulder and have at your side, not your back.
