Another gas gun soon to be released by Tokyo Marui is the HK45



Gun History

Developed from the start to be a defensive handgun, the HK45 Compact will easily fit the requirements for a concealed carry handgun. With an overall length of 7.2 inches, height of 5.06 inches and a width of 1.14 inches, this gun is a true compact but not a sub-compact. Like the USP, the HK45C can be purchased with any of 10 trigger systems, but this gun came with (at my request) the LEM (Law Enforcement Modification) trigger that offers a short length, hammer-fired, double-action-only (DAO) mechanism that’s easy to train with and shoot.

The LEM is my preferred action due to its simplicity and ease of use. Other variants offer decock and safety levers for both right- and left-hand shooters. Since the HK45C comes standard with an enlarged, contoured, ambidextrous magazine release as well as slide lock levers on both sides of the gun, the LEM makes this a true “everyman’s” pistol.





To offer the power of the .45 cartridge in a compact as well as controllable package, HK integrated a very effective recoil reduction system into the pistol’s design. This system can potentially reduce as much as 30 percent of the gun’s felt recoil, an important feature for rapid follow-up shots! While none of us likes to think that we will miss, it can happen, especially during a gunfight. Helping shooters get back on target fast is a desirable feature.

Both the HK45C and its big brother, the HK45 are rated for +P ammo and offer a service life of at least 20,000 rounds. Both pistols also have polygonal rifling in the barrel as well as a rubber O-ring at the muzzle for increased slide-to-barrel lock, which increases accuracy, velocity and service life. For those agencies or individuals that have special needs, a threaded barrel can be added for the addition of a suppressor.
