40 Smith and Wesson handgun ammunition is extremely popular among law enforcement and shooters that crave a good round for self-defense. 40 cal rounds provide more energy than 9mm Luger while delivering nearly identical drift and drop and accuracy.

40 cal rounds come in a wide range of weights, from as light as 135 grain to as heavy as 200 grain. Although, most shooters would consider 165 or 180 grain standard for most range or self-defense use bullets. In terms of muzzle velocity, you'll find the fastest .40 SW rounds travel at about 1,200 feet per second. Larger rounds pack a punch with some 180 grain rounds promising close to 1,100 feet per second of muzzle velocity, good for more than 450 foot-pounds of energy.
