Excluding being smaller in length/height and the use of a slim line grip
profile, the HK45 Compact (HK45C) is nearly identical in features to the
full-size HK45. The HK45 Compact was developed as a possible candidate for
the Joint Combat Pistol (JCP) and Combat Pistol (CP) programs administered
by the U.S. military in their search for a service handgun. These programs
were suspended before completion and no pistols were selected. The HK45
Compact uses a HK proprietary O-ring barrel for precise barrel-to-slide
lockup and optimal accuracy. HK45 barrels are made using the famous HK
cold-hammer forging process for superior performance. Using HK's unique
internal mechanical recoil reduction, system reduces the recoil forces
imparted to the weapon and shooter by as much as 30%, improving shooter
control during rapid firing and increasing component service life. Variant
7 is a double action without control lever (no manual safety/decocking
lever). This model ships with 3 magazines and night sights.
