“With its relatively low ammunition capacity and not-a-revolver-not-an-auto-loader design, this lightweight, three-inch double-barreled handgun really has only one purpose in mind: punish your hand like a psychotic school marm wielding an aircraft grade aluminum ruler.” Just kidding. The stated singular purpose: “last-ditch self defense in extremely close quarters where one or two shots may be all that’s needed to end or escape from an attack.” That’s americanhandgunner.com‘s not-so-surprisingly positive “exclusive” take on the DoubleTap Tactical Pocket Pistol (reviewed by TTAG here). While I get the idea that “a” gun is better than no gun, a “better gun” is better than a “less good gun.” Nine millimeter Kahr PM-9 all day long baby. But if I was going to carry two guns, then sure, why not? But then why? Aren’t I better off carrying a spare mag for my compact .45-caliber 1911? What’s your take on carrying a back-up gun?
