Umarex Heckler & Koch HK45 Air Pistol (5.8185)

The Umarex HK45 air pistol is a high-quality licensed replica from the renowned brand Umarex, accurately replicating the Heckler & Koch 45 prototype. The model is crafted with attention to detail: a full metal slide provides authenticity, and the frame features a Weaver/Picatinny rail for mounting under-barrel or other additional accessories. The ergonomic polymer grip has comfortable overlays, ensuring a secure hold during shooting.

Structurally, the pistol is equipped with a magazine with a capacity of 19 BBs. The power source is a CO2 cartridge, which in this model is located in the rear part of the grip and is separate from the magazine. The correct loading sequence is: first install the cartridge, then the magazine can be removed and loaded. Loading is simple: the follower spring lever is locked in the slot, after which the BBs are fed into a special opening on the side panel of the magazine.

The technical specifications of the model meet the requirements for recreational shooting: the initial velocity is 125 m/s, and the maximum muzzle energy is about 3 J, which guarantees comfortable and safe operation within the device's intended purpose.
