Underwood Ammo XTP jacketed hollow point ammunition in .40 S&W delivers reliable performance for self-defense and training. Loaded to 1300 fps with a 155-grain XTP bullet, this round generates 582 ft-lbs of muzzle energy and carries proven stopping characteristics in a compact, manageable package. The nickel-plated brass cases are reloadable and non-corrosive, making it practical for shooters who reload or simply want long-term storage reliability.
