I use a similar bag when I travel. Mine has a pouch on the backside that I can slide my Ruger SP 101 into and it is completely out of sight. I do that because it makes my pistol easier to access while driving. It keep my wallet, my phone, and house keys in there as well. If I make a pit stop I take it with me, and I haven't had any problems. The other reason I use the bag when traveling is that all of my stuff stays in there when I get to where I'm going. That way when I get home I'm not wondering where I left something. I agree with Bassbob and fordag that carrying off body on a daily basis can be a hazard. I also use the same bag when I go hunting. It's just easier to keep the stuff I might need while I'm out in the woods organized in a small, comfortable shoulder bag.
