The CO2 pistol HK45 is a scale replica of the HK45 Auto self-loading pistol with a metal slide and a strong CO2 NBB (Non-BlowBack) system.
The lower part of the weapon and the ergonomic grip are made of plastic. The latter features finger grooves and is slightly textured for a secure grip. The CO2 cartridge is housed in this part without the need for tools.
Additionally, the CO2 HK45 has a Picatinny rail, allowing for the attachment of optional accessories.
