The HK45 was developed as a product improvement of the highly
regarded USP45, first released in the 1995. The Caliber .45 ACP HK45
includes several user-inspired enhancements including changeable grip
panels (backstraps), a Picatinny MIL-STD-1913 accessory rail, better
ergonomics, and more ambidextrous controls.
Along with the HK45 Compact, the HK45 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 to replace the 9-millimeter M9. These programs were
suspended before completion and no pistols were selected.
The HK45 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 combines the accuracy, modularity,
reliability and minimum 20,000 round service life of the famed USP45
series with the improved ergonomics of the P2000 series pistols. HK45
models can be also be fitted with threaded barrels for use with muzzle
mounted sound suppressors.
Each HK45 comes standard with an extra backstrap;
medium and small interchangeable backstraps ensure an optimal fit for
most shooter’s hands and complement the ergonomic profile grip.
An improved USP-style control lever, a combination
safety and decocking lever, is frame mounted on the HK45 and is quickly
accessible. The HK45 control lever has a positive stop and returns to
the “fire” position after decocking.
By using the modular approach to the internal
components first pioneered by HK on the USP, the control lever function
of the HK45 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 HK45 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 for improved double action trigger pull.
Extensively tested and operationally proven, the HK45
Series is a new paradigm for Heckler & Koch handgun design and is
currently being assembled from U.S. and German made components at HK’s
American manufacturing facility in Newington, New Hampshire.
