Heckler and Koch HK45 V1 Pistol
The HK45 V1 pistol 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 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. 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.
Cold Hammer Forged Polygonal Bore
During the 1960s, Heckler & Koch perfected the famous polygonal profile barrel technology. Conventional lands-and-grooves rifling allow propellant gasses to escape around the front of the bullet as it is fired from the barrel muzzle. A polygonal bore profile effectively seals propellant gases behind the bullet—increasing bullet velocity.
An added benefit of a polygonal barrel is its resistance to wear. A polygonal barrel will normally outlast a conventional “lands-and-grooves” barrel by thousands of rounds. Polygonal barrels were one of the many radical design elements used on the HK P7 series pistol and this same breakthrough technology is present on all current HK handguns.
Reinforced Polyamide (Polymer) Frame
A radical new material used on the P9S pistol in the late 1960s, advanced polymers were soon used as major components and assemblies on a variety of HK products — including the receivers of MP5s in the 1960s. HK polymer molding technology led to the introduction of another synthetic framed HK handgun, the futuristic-looking VP70. Heckler & Koch pioneered the use of polymers more than fifteen years before competing firms. Today, HK remains a technology leader in the use of innovative and high-strength polyamides.
CLEARING THE PISTOL
The HK45 series of pistols are not considered “clear” or safe unless: 1. The control lever (if applicable) is on “safe” and;
2. The magazine is removed from the pistol and;
3. The slide is locked to the rear and;
4. The chamber is free of brass or ammunition
To Clear the HK45 / HK45C
- Make sure fingers are outside of the trigger guard and the pistol is pointed in a safe direction at all times!
- Engage control lever (if applicable) - press the control lever upwards until the “S” (safe) aligns with the reference line located on the frame.
- Remove magazine - depress the magazine release lever and remove the magazine from the pistol.
- Open and lock slide - while keeping the pistol pointed in a safe direction, lock the slide open by
- pulling the slide rearward as you press the slide release upward. Watch for a cartridge or empty
- case to be ejected from the pistol.
- Inspect chamber - inspect chamber for the presence of a cartridge or empty case by:
- Visually viewing chamber through the open ejection port and;
- Physically inserting a finger into the chamber through the ejection port to check for the presence of a cartridge or empty case.
- Remove any cartridges or empty cases from the chamber or from within the pistol.
The HK45 and HK45 Compact were developed as product improvements to the highly regarded HK USP45 and USP45 Compact family of pistols, first released in the 1990s. New user-inspired enhancements found on the HK45 and HK45 Compact are also found on recent Heckler & Koch semi-automatic pistols, including the P2000, P2000SK (Subcompact), and P30.
The HK45 and HK45 Compact were also developed as possible candidates 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 9mm M9. These programs were suspended before completion and no pistols were selected.
