The baseline ballistics from a handgun platform is 1,800 fps muzzle velocity with 2,338 ft.-lb. of muzzle energy. However, when the round is shot from a 20-inch rifle barrel, the transformation is impressive. The chronograph clocked our 10 shots at an average of 2,189 fps, a nearly 300 fps gain when compared to a handgun. The increase in speed translates to a muzzle energy of 3,458 ft.-lb. That’s enough power to knock over a building, as well as any animal walking the earth.
