The grasshopper mouse:

The GHM9 is a 9mm semi-automatic carbine. It was conceived as an entry level carbine for sport shooting. The excellent intuitive ergonomics and crisp trigger make this an outstanding choice for competitions and dynamic shooting disciplines but also for use by police and law enforcement.

The GHM9 complimented by the integrated hydraulic recoil buffer system found on other B&T products that reduces recoil and enhances handling. The name GHM and in typical Swiss understatement, it stands for Grasshopper Mouse, homage to the North America carnivorous rodent which is known to eat Scorpions.

The GHM9 is available in several different versions:
Compact version
Integrated suppressed version
30-round B&T magazine
Any size Glock pistol magazines
