Product Overview

Heckler & Koch HK45

4.5 mm (.177) BB, CO₂, < 3.0 J

The HK45 is a modified version of the proven USP .45, which was developed by Heckler & Koch to meet the requirements of U.S. forces.

Airgun fans will be fascinated by the many new features of this licensed replica, which offers exciting opportunities in their sport. The heavy metal slide provides a realistic weight, and the high-strength polymer frame ensures excellent handling. With its authentic markings this replica is also visually impressive.

But the shooting range is where the HK45 shows what it can do. The highly efficient 12 g CO₂ cartridge propels the magazine’s 19 steel BBs with a maximum energy of 3 joules to their target. The safety lever on the left is easy to reach with your thumb.
