Named after the Grasshopper Mouse, a small, yet savage carnivorous rodent living in the Southwest United States; it is famous because of its favorite snack – Scorpions – and is immune to their venomous bite. The GHM is a cost-effective, competition-oriented PCC featuring many of the same great qualities that made the APC9 so successful, while providing the user with additional levels of flexibility and modularity. The Gen 2 allows users to change barrel lengths, handguards and stocks, as well as the ability to add an SD kit, among other accessories. Like many B&T SMG’s, the GHM9 accepts all APC9 PRO lower receiver groups, meaning it can be equipped to accommodate Glock magazines, SIG P320 magazines or proprietary B&T magazines, by simply switching the non-serialized lower receiver group. All GHM9s ship as pistols and include a magazine and flip-up back up sights.
