Huben GK1 Pistol



Inspired by Gregor Kamenšek’s world-famous Huben modification, which has garnered the interest of so many of you, Huben itself took the hint and got its hands on developing the ubiquitous K1 Pistol – now the Huben GK1 Pistol.

The Huben GK1 Pistol is a unique format in the World of airguns, combining the action of the K1 – which provides extreme power in semi-auto and features a very large magazine capacity- and the pistol format. Weighing just 1.2 kg and having a total length of just 325mm, the GK1 will feature adjustable power, iron sights, and also a dovetail rail for optics.

The GK1 itself won’t be suppressed. However, you can always add one with its. 1/2 x 20 thread size. Adding an integral suppressor would defeat the purpose of the compact format, but this is compensated by the fact that… it is a K1 pistol! This means unheard-of power for this size, and superb accuracy as well. Following the style of the Special Edition K1, Huben has furnished the GK1 with an ergonomic walnut grip.

It has also been disclosed that the GK1 will be available in calibers .177//4.5mm, .22//5.5mm, and .25//6,35mm! This means that the GK1 will add a new caliber to Huben (the .177//4.5mm).

Please Note: ***Initial payment of $100 is a pre-order reservation only. The actual retail price is $1,250. We will contact you to make the final payment when the pistol is available for shipping.
