Huben GK1 Mini V3+ | Semi-auto PCP Pistol Toy

The long awaited Huben GK1 Mini is finally available!
This powerful semi-automatic pistol is not only beautifully finished, but has a well-thought-out design!

Ultra-compact footprint for fast target acquisition and easy carry — a true “go anywhere” air pistol that still packs meaningful energy.
Multi-caliber platform: available in .177 (4.5 mm), .22 (5.5 mm), .25 (6.35 mm) and even a .30 (7.62 mm) caliber to match your shooting style and local rules.
Semi-automatic action with high-capacity magazine design carried over from the GK1 series for reliable feeding and fast follow shots.
Built for tuning: adjustable power settings and compatibility with aftermarket regulators and tuning parts for flatter shotstrings and tighter groups.
Optics-ready: 11 mm dovetail on the barrel shroud for red dots or compact scopes, plus adjustable iron sights for quick zeroing.
The ergonomic walnut grip, complete with textured surfaces and finger grooves, ensures a secure and comfortable hold, enhancing handling and control.

Semi-auto Shorty

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!

First annouched as the "Shorty", this compact version of the GK1 has now come to the market as the GK1 Mini!

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.
