Trailblazer Firearms has introduced the .22 WMR version of their LifeCard folding single barrel single shot derringer. The first version of LifeCard pistol was introduced a little over a year ago and so far it was available in .22 LR only. This is a really compact and discreet little handgun. As the manufacturer states, it is “no bigger than a stack of credit cards“.

To be more precise, the advertised dimensions of the LifeCard .22 WMR (when folded) are as follows: Length – 3.375″, Height – 2.125″, Thickness – 0.5″. The dimensions of a standard credit card are 3.37″x2.125″x1/32″. So the LifeCard has a thickness of a stack of 16 cards. It is also quite lightweight weighing less than 7 oz.

The LifeCard pistol has a single action only trigger mechanism which means you need to manually cock the striker/bolt before each shot. This derringer also has a built-in safety mechanism that will prevent accidental discharge when it is folded. Both the unfolding latch and barrel latch are present on either side of this handgun making it completely ambidextrous. According to the manufacturer, this new model has a new barrel latch design which no more requires to pull back the barrel latch to close the barrel. The gun also has a compartment inside the grip which allows storing three .22 WMR cartridges. There is also a lanyard loop on the grip.

The barrel of this little handgun is machined out of 4140 steel. The frame and grip are also machined parts made of aluminum. The steel and aluminum parts feature Isonite and hard coat anodized finishes respectively.

The LifeCard .22WMR pistol is listed on the Trailblazer Firearms website at an MSRP of $399.

Now let’s think about what practical use this gun can have? It is a single shot derringer which is the least amount of firepower one can imagine (next to a single shot muzzleloading gun). On the other hand, you probably won’t find a more compact weapon that shoots the .22 WMR cartridge. Another advantage is its discreet nature – I bet not many people can identify a gun in a folded LifeCard.

Of course, this gun should not be considered as a primary concealed carry weapon, but maybe it won’t hurt to have one among your EDC items as a last ditch backup gun? Or is it marketed for people who consider it less likely to find themselves in a gunfight but at the same time think that if it happens any gun would be better than no gun and literally don’t want to bring a knife to a gunfight? Tell us in the comments section what do you think about the LifeCard?
