HK45
The HK45 was designed as a refinement of the highly praised USP45, first introduced in 1995. A Caliber .45 ACP HK45 includes numerous user-inspired improvements, such as a changeable grip panel (backstraps) and an accessory rail for Picatinny MIL–STD-1913 with improved ergonomics, as well as more control options that are ambidextrous.
Alongside the HK45 Compact, it was also the HK45 was created as a possible possibility to be a candidate for Joint Combat Pistol (JCP) and Combat Pistol (C.P.) programs operated by the U.S. military in their search for a new military handgun that could replace the 9 millimetre M9. However, these programs were stopped before they were completed, and no handguns were picked.
The HK45 features an H.K. exclusive O-ring barrel that allows for exact barrel-to-slide lockup and maximum precision. In addition, the barrels for the HK45 are manufactured using the renowned H.K. cold-hammer forging method to ensure top performance.
The HK45's exclusive internal mechanical recoil reduction system, HK45 reduces the forces of recoil that are transferred to the shooter and weapon by up to 30%, increasing the shooter's control during firing speed and extending component life span. The HK45 can fire a normal .45 ACP ball through +P ammunition. The HK45 offers the precision of the P2000 series with the modularity, reliability and minimum 20,000-round service life of the renowned USP45 series, with the enhanced performance of pistols in the series P2000. HK45 models can also be equipped with barrels with threads to use with muzzle-mounted sound suppressors.
Every HK45 is equipped with an additional backstrap. Small and medium-sized backstraps are interchangeable to guarantee a perfect hand fit for most shooters and complement the ergonomic grip.
A more modernized control lever that is USP-style is a safety lever, and a decocking lever is attached to the HK45 and is easily accessible. The lever controls have an adjustable stop that is returned in its "fire" position following it has been decocked.
With modular approaches to internal components, first developed by H.K. in the USP, The control levers of the HK45 can be switched from the left side to the left side of the pistol to accommodate shooters with left hands (additional components are needed). Left and right mounted control levers offer safety or decocking functions depending on the requirements and can be added to the pistol by removing parts. For accurate ambidextrous operation, it is possible to have a control lever also be placed to both sides, if needed.
It is ideal for personal defence. It is available in or could be changed to various variations with different trigger firing options that include double-action/single-action (DA/SA) or DAO (double actions only). The DAO option uses the distinctive Heckler & Koch LEM (Law Enforcement Modification) firing system to provide a more efficient double trigger pull.

Specifications:
The specifications of the Heckler and Koch HK45 pistol.
- The Heckler and Koch HK45 receives full marks for its frame and trigger design (-0 points). Although it's not equipped with replacement grip plates, like that of the SFP9 or the P30 frame, it's design and ergonomics tick all the boxes.
- Contrary to the previous USP frame that was previously used, unlike the USP frame, HK45 has three finger grooves on the front, anatomically adjustable flanks, and a reversible backstrap. The circumference is smaller than the previous generation polymer models with 45 calibres due to its slimmer magazines with less than 23 millimetres.
- Its trigger is somewhat elusive (-2 points). The long trigger path is apparent when you are in double-action mode. The trigger pull pre-tensioned is 1,950 grams, which is the ideal weight for a pistol made of polymer - however, the trigger release is unclear.
- Nothing of note happened during this review segment Safety/Cycling, So there were no deducted points either (-0 points). This pistol's sights have three luminous yellow dots. The sighting system, which is a bit pared-down, can be used as a standard pistol. Only the rear sight can be adjustable to allow the lateral offset. The notch is extremely broad (-1 one point).
- Most controls are mounted to either side of the firearm. However, the safety/decocking lever is located to the left (-1 points). The slide stop lever and the catch for magazine releases are easy to operate using just one hand and are a sign of excellent ergonomics.
- However, getting rid of the slide stop lever while stripping the weapon is more complicated than with earlier USP models. The finish of the weapon is high-end (-0 points). Our HK45 pistols earned 48 points of precision (-2 points).

Americans are awed by the reliability and high quality of the products produced by Oberndorf mainly. However, the relatively high price for a brand new pistol was the sole bone of contention for a lengthy period. It cost more than 1,000.00 USD. The Heckler & Koch HK45 was nearly twice as costly as the comparable polymer model from GLOCK and Smith & Wesson.
In terms of engineering, the Heckler and Koch HK45 is a slightly more modernized variant that is a bit more advanced version of its USP generation. However, the Heckler & Koch HK45 has its advantages with its ergonomics that are improved in particular. Engineers from Oberndorf created the HK45 to serve military personnel in the U.S. military. It locks the ejection port using an upgraded Browning system.
A spring unit encapsulated that has a buffer to compensate for recoil. The polymer frame was specifically designed to operate ambidextrously. As a result, you can find slide stops, and the magazine catches in both the front and back of the gun.
However, the safety and decocking lever only sit to the left. Therefore, no safety lever can be operated manually on the trigger model V3. However, the lever can be used to release the weapon. This HK45 can be purchased in black frame colours, the RAL8000 (green-brown), and olive.
