Introduced in 1990 to bridge the gap between 9mm and .45 ACP, 40 S&W ammunition drives a 155- to 165-grain bullet at roughly 980–1,150 fps, delivering about 330–420 ft-lbs of energy with a recoil impulse that many shooters find more controllable than larger calibers. Full metal jacket (FMJ) rounds cycle smoothly in semi-autos for cost-effective target practice, while jacketed hollow point (JHP) loads are engineered for rapid expansion and deep penetration when it matters most. Favored by law enforcement and home-defense advocates alike, 40 S&W offers a balance of stopping power, magazine capacity and muzzle blast. Sportsman’s Outdoor Superstore stocks 40 S&W ammo from leading manufacturers—browse grain weights, bullet constructions and velocity ratings, then secure your order online with competitive pricing, fast shipping and secure checkout.
