No matter how you spell it, a Derringer is a useful little thing. It’s a deep concealment firearm that’s a whole lot better than a sharp stick, should push come to shove come to imminent, credible threat of death or grievous bodily harm. Same goes for the new breed of .380’s and tiny nines. Not to mention the venerable snub-nosed revolver. They’re all great guns for gunfights — provided you don’t need a lot of capacity or accuracy. Which you probably do but whatchugonnadu when they come for you?
