If you’re looking to add a little something (pun intended) to your everyday carry arsenal, then you need to take a look at the LifeCard .22LR ($400). The LifeCard is .22-caliber single shot pistol that folds into the size of a credit card. It features a no snag design, and a frame and grip that are constructed from machined aluminum billet that’s been hard-coat black anodized. While the barrel, bolt, and trigger are made of steel. The entire gun measures just 3.375 inches x 2.125 inches x .5 inches thick and weighs just 7 ounces. There’s also storage in the handle for up to four rounds.
