I have a Hi Standard 22mag DA derringer. I also have the wallet that came with it. As long as I keep them seperate they are legal. The minute I put the gun into the wallet, it becomes an evil thing with a mind of it's own. (Per BATF) They are concerned it might give a citizen an element of surprise over a poor disadvantaged victim of society. It might have some merit if it could be carried in the wallet, but carried as a BUG or primary is a poor choice. It is certainly better than nothing, and if it were all I had, I'd carry it! However, there are too many better choices for that role available, that are lighter, sufficently powerful, smaller, more accurate, have greater firepower, and are much faster to get into action than most derringers. Easy choice for me!
