The Springfield Armory Kuna .40 S&W pistol (brand part no. KN90640B) is a compact, roller-delayed pistol from Springfield Armory built for stability in a portable package. The roller-delay operating system reduces felt recoil and improves control, and the 6-inch threaded barrel ends in a multi-port muzzle brake. Hybrid flip-up sights, an M-LOK handguard and fully ambidextrous controls round out the package. It is a fit for the shooter who wants a flat-shooting .40 S&W in a home-defense or range pistol.
