About this product
The Trailblazer LifeCard is a genuinely unique single-shot pistol built to fold flat into a shape roughly the size of a thick credit card, chambered here in .22 WMR. This is the higher-powered variant of the LifeCard line, offered only in the all-aluminum construction rather than the polymer-bodied .22 LR version, since the more powerful WMR cartridge requires the added strength of an aluminum frame.
How does a folding single-shot pistol work?
The LifeCard folds along a hinge so the barrel lies flat against the grip and trigger, dramatically reducing its footprint for storage or carry, and Trailblazer specifically engineered the design so the pistol physically cannot fire while folded — a mechanical safety feature built into the platform rather than relying solely on a manual safety switch. To fire it, the shooter unfolds the pistol, loads a single round, and closes the action, similar in concept to opening a folding knife before use.
What are the full specs?
Folded, the LifeCard measures just 3.375 inches long, 2.125 inches tall, and 0.5 inches thick, weighing only 7 ounces — genuinely pocketable dimensions that few other firearms can match. It's built from 4140 pre-hardened steel for the barrel and trigger and aluminum for the frame and handle, entirely machined from billet stock, with a corrosion-resistant Isonite finish on the steel components and hard-coat anodizing on the aluminum. The barrel measures 2.5 inches, and the handle has built-in storage for three extra rounds, so a total of four rounds of .22 WMR can be carried in the pistol itself between reloads. Trailblazer backs the LifeCard with a lifetime warranty, and it's fully ambidextrous.
Who is the LifeCard built for?
This pistol is best suited to shooters who want the absolute smallest, most easily stashed backup or novelty firearm on the market, whether as a genuine last-resort backup gun, a glovebox or bag companion, or simply a conversation-piece firearm built around genuinely clever engineering. Because it's single-shot with a 4-round total on-board capacity between the chamber and grip storage, it is not a substitute for a proper defensive pistol as a primary carry gun, and should be thought of as a backup or novelty option rather than a main sidearm.
Because this is a firearm, it cannot ship to your home address. It transfers to a licensed FFL dealer near you, where you will complete a background check and the required paperwork in person before taking possession. California maintains its own certified handgun roster; buyers should confirm current roster status for this specific .22 WMR configuration with their FFL before ordering, since the .22 WMR and .22 LR versions of the LifeCard can be tracked as separate models on state rosters.
The .22 WMR chambering gives this variant meaningfully more stopping power than the standard .22 LR LifeCard, at the cost of requiring the heavier, more expensive all-aluminum construction rather than the lighter polymer-bodied .22 LR model. For shooters who specifically want the LifeCard's novel form factor but also want more power than .22 LR provides, this is the only way Trailblazer offers that combination.
The fully machined billet construction, rather than cast or stamped parts, is part of why Trailblazer can back the LifeCard with a lifetime warranty despite its unusual folding mechanism, and the corrosion-resistant Isonite and hard-coat anodized finishes are chosen specifically to hold up to the kind of pocket, bag, or glovebox carry this pistol is designed for, where it will regularly contact keys, coins, and other hard objects.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost. You complete the background check and paperwork with the dealer when you pick up.
California buyers: handguns must be on the California roster for delivery to a California FFL, a Firearm Safety Certificate (FSC) and DROS are handled at the dealer, and the 10-day waiting period applies. Out-of-state buyers receive the firearm through their own local FFL under their state's rules.
