The Trailblazer Firearms LifeCard 22 is the new standard for Discreet Carry – a folding, single-shot rimfire pistol that’s no bigger than a stack of credit cards. At .5 inches thin and weighing less than 7 ounces, LifeCard 22 will be the last gun you’ll leave behind. While a folding handgun no bigger than a smartphone sounds like a thing of the future, the Trailblazer LifeCard isn’t a gimmick. This high-quality folding single-shot .22 caliber pistol is designed for emergency use and extreme concealability. Not only would it serve well as a hidden backup gun, it’s also incredibly fun to shoot.
