Based on the company's unique KH9 submachine gun, which is chambered in 9mm, Brugger & Thomet offers its GHM45 Pistol, which brings a big-bore .45 ACP option to American consumers. Each Brugger & Thomet GHM45 Pistol is built with a specially designed trigger system unlike any other sub-gun system on the market. The first trigger press provides users with a long, double-action pull that's followed by short, single-action pulls, providing many of the same safety and accuracy benefits offered in popular DA/SA handguns.
