World's smallest .45 caliber pistol

Posting in Design

The DoubleTap handgun is only 5/8ths of an inch thick and weighs 14 ounces.

You're looking at what's perhaps the world's most compact .45 caliber pocket pistol.

Despite sporting dimensions similar to a standard smartphone (5/8ths of an inch thick) and weighing only 14 ounces, the DoubleTap features a no-snag, hammerless design (firing mechanism is internal) that's capable of the kind of precision and efficiency offered by high-performance .45 caliber handguns. And, according to the manufacturer, Heizer Defense, you won't find a slimmer and lighter pocket pistol anywhere on the market.

For gun enthusiasts, here's a rundown of the handgun's features as highlighted on Heizer's website:

  • Available in .45 ACP or 9MM
  • A patent-pending progressive barrel porting option that cuts muzzle rise and recoil.
  • A one-of-a-kind double-action trigger system that utilizes ball bearings for a smooth action and crisp trigger pull.
  • Designed to hold two rounds in the chamber and two additional spare rounds inside the handle

Buyers can choose between an aluminum model that starts at $500 or one made out of titanium with a MIL-STD finish, the same used on military aircraft, for a protection against corrosion and wear damage for $730.

The DoubleTap is slated to go on sale in the first quarter of 2012.

Here's some videos showcasing the new firearm:
