The Huben GK1 Custom Regulated GK1 V3+ Mini represents the most refined evolution of the GK1 Shorty platform, combining the ultra‑compact 6" barrel format with the advanced V3+ architecture that made the GK1 a benchmark in high‑power air pistols. Inspired by Gregor Kamenšek’s renowned modification and developed by Huben, this Mini variant preserves the remarkable energy output, high‑capacity magazine system, adjustable power settings, and exceptional efficiency of the GK1 - now in a lighter, more agile form that feels perfectly balanced in the hand. Available in .177, .22, .25, and .30 calibers, it delivers rifle‑like authority from a pistol platform without sacrificing handling, control, or versatility.

The “Regulated” designation indicates that this V3+ configuration includes the dedicated Regulator Kit developed by Wolfiek Group, installed specifically to work in perfect harmony with the GK1 V3+ platform. While the original GK1 V3+ is famously unregulated to achieve extreme peak power and impressive efficiency, this version introduces a regulator system that transforms the shooting behavior by dramatically increasing shot‑to‑shot consistency and air efficiency, while retaining the mechanical strength and adjustability that define the GK1.

This regulated configuration combines the legendary K1‑derived action of the GK1 with the stability of a regulated air system. The kit includes the regulator, forward manometer, K1‑style fill port, and reservoir adapter, all precisely selected to integrate seamlessly with the GK1 V3+ architecture. Any GK1 V3+ can be converted into this regulated format using the same kit.

The result is a GK1 V3+Mini that can be safely and precisely tuned across an exceptionally wide power range using both the regulator and the power wheel - from very low energy levels suitable for restricted markets such as 6 FPE and 7.5 Joules, to the higher performance levels the platform is known for. This makes the GK1 Mini V3+ Regulated uniquely adaptable to various international legal requirements while delivering an even more refined, consistent, and efficient shooting experience.
