Inspired by Gregor Kamenšek’s world-famous Huben modification, which piqued the interest of many, Huben himself took the hint and began developing the ubiquitous K1 pistol – now the GK1. v3 with carbon muffler.

The GK1 pistol is a unique format in the world of air rifles, combining the action of the Huben K1 – which offers extreme power in semi-automatic and features a very large magazine capacity – and the pistol format. Weighing only 1.2 kg and with an overall length of 325 mm, the GK1 features adjustable power, aiming equipment and a dovetail rail for optics.

This is effectively a K1 pistol! This means unprecedented power for this size, as well as excellent accuracy. In the style of the Special Edition K1, Huben has fitted the GK1 with an ergonomic walnut handle.
