The PKO-45 or Pocket 45, is one of the slimmest semi-auto .45 ACP on the market at just 0.8 inches wide and weighs approximately 25 ounces.

Heizer’s new pocket pistol is made with 100 percent U.S. Aerospace grade stainless steel. There are no plastic or mimed parts on the pistol. It boasts a revolutionary fixed-barrel-under-the-guide-rod configuration, resulting in less recoil felt by the operator.

The PKO-45 also features a snag-free design, an internal hammer/single action, and a front strap safety with an additional thumb ambi-safety. It has 5+1 capacity with a flush magazine, and 7+1 capacity with the extended magazine.
