When it comes to personal defense or survival situations, a firearm can be a force multiplier, but only if its on-hand. Trailblazer Firearms has developed a sub-half-pound pistol that folds to the dimensions close to that of a credit card or photo ID. The LifeCard is a tilt-barrel, single-shot pistol that fires .22 Long Rifle cartridges from a 2.5” barrel that’s treated for corrosion resistance. Within the gun’s hardcoat-anodized aluminum grip frame is a sliding cover that houses several cartridges as reloads. Using the svelte pistol requires a bit of dexterity, and its chambering and capacity have their limitations. But the LifeCard is a highly portable and easily concealed, making it a backup likely to be carried, not left behind.
