OK, it can be a lifesaver depending on how you use it.
LifeCard .22LR is Trailblazer’s latest (and probably the smallest) addition to its list of arsenals. It’s a single-shot pistol that, when folded, is about the size of a credit card. Its frame and grip are made from machined aluminum billet; the barrel, bolt, and trigger are made of steel.
The handle can store up to four rounds and weighs just about 7 ounces.
It would be more fun if this is as powerful as the Noisy Cricket (video below to jog your memory).
