Smaller in length and height than the standard HK45, the HK45 Compact
(HK45C) uses a slim-line grip profile, otherwise is nearly identical in
features to the full-size HK45.
Like the 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
new service handgun. These programs were suspended before completion and
no pistols were selected.
The HK45 Compact uses an 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
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.
Capable of firing standard .45 ACP ball through +P
ammunition, the HK45 Compact has an 8-round magazine capacity but can
also use 10-round magazines, including those designed for the full-size
HK45. The HK45 combines the accuracy, modularity, reliability, and
minimum 20,000 round service life of the renowned USP45 Compact with the
improved ergonomics of the P2000 series pistols. HK45 Compacts can be
also be fitted with threaded barrels for use with muzzle mounted sound
By using the modular approach to the internal components first
pioneered by HK on the USP, the control lever function of the HK45 and
HK45C can be switched from the left to the right side of the pistol to
accommodate left-handed shooters (additional parts required). Left and
right mounted control levers provide safety and/or decocking functions
as required and can be fitted to the pistol simply by changing parts.
For true ambidextrous use, a control lever can also be mounted on both
sides of the pistol if required.
Well-suited for personal defense use, the HK45C is
available in, or can be converted to, a wide variety of variants that
use different trigger firing modes, including double action/single
action (DA/SA) and DAO (double action only). The DAO mode uses the
unique Heckler & Koch LEM (Law Enforcement Modification) firing
system, providing an enhanced double action trigger pull.
Extensively tested and operationally proven, the HK45C
is currently being assembled from U.S. and German made components at
HK’s American manufacturing facility in Newington, New Hampshire.
