Semi-auto

The Huben GK1 is a semi-automatic PCP pistol. So for every time you pull the trigger, the GK1 fires a shot.
This makes the GK1 great for fast, dynamic shots!

Design

What is striking about the Huben GK1 is of course the design.
The GK1 has a beautifully finished design and at 1.2 kg it is not a super heavy pistol.
In addition to the standard sights, the GK1 has 11mm rails for optics such as red dots or a pistol scope.

The Huben GK1 comes in a sturdy case.

Power

The Huben GK1 is adjustable in power.
This allows you to make the pistol very efficient and air-saving, or you can open it up so far that the pistol is as powerful as a full-fledged rifle!

Adjusting the power is very easy with a simple adjustment screw.
This gives the GK1 a power range of at least 6 to 55 and 60 joules! (depending on caliber)

Magazine capacity

The Huben GK1 is based on the mechanism of the Huben K1.
With this mechanism the internal magazine has a gigantic capacity for a pistol of 17 shots in 6.35mm and 19 in 5.5mm!

This "revolver" magazine is easy to load via the loading port on the magazine.

Fill-pressure

The Huben GK1 has an 85cc tube with a filling pressure of up to 300 bar.
This allows the Huben to achieve approximately 30-40 shots at average settings.
This may of course differ with different desired power, ammunition and caliber.
