The Holy Grail of airguns!

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 GK1.

The GK1 pistol is a unique format in the world of airguns, combining the action of the Huben 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 325mm, the GK1 will feature adjustable power, iron sights, and a dovetail rail for optics.

This is effectively 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.
