HP22 and HP25 The
HP22 and
HP25 are small semi-automatic
pocket pistols chambered in the
.22 Long Rifle or
.25 ACP cartridge, respectively. They are blowback-operated pistols and come with 3-inch barrels. Optional five-inch 22LR barrels are available. The frame is Zamak zinc alloy. The detachable barrel is a steel sleeve inside of an alloy casing with an integral front blade sight and vented rib. The vented rib continues back along the alloy slide to the windage adjustable rear sight. They are
hammer-fired
single-action pistols. They have a slide-mounted manual firing pin block safety in addition to a regular manual slide combination hold open and safety. The pistol includes a
magazine disconnect feature, which prevents the gun from firing without a magazine. The magazine cannot be removed without engaging the manual slide safety. The HP22 feeds from a single-stack 10-round
magazine, and the HP25 feeds from a single-stack nine-round magazine. The HP22 is designed for use with standard-velocity .22 Long Rifle ammunition only. They are available in satin nickel or matte black finish. A primary change of the HP22A and HP25A models was the addition of a half-cock hammer position, as well as internal parts changes that are not compatible with the previous models. ==Accessories==
