Introduced in 1990, this cartridge was developed primarily for the law enforcement market. Guns chambered for the .40 S&W combine high-capacity magazines with acceptable stopping power. It is slightly less powerful than the 10mm Auto — which reduces the probability of over-penetration — but is considerably easier to control during rapid fire.

As a result of testing to optimize terminal ballistics on the 10mm Auto, the FBI adopted a reduced power loading. Smith & Wesson subsequently offered a cartridge with a similar power level chambered in a pistol with a high-capacity magazine.

In an amazingly short period, the .40 S&W has gained wide acceptance throughout the U.S. in the law enforcement field.

The .40 S&W is an easy cartridge to load and gives excellent performance with the complete line of Accurate's handgun propellants.

This data should also prove suitable for loading the .41 Action Express. The .41 Action Express has a rebated rim case permitting the owner of a 9mm handgun to change calibers by merely replacing the barrel and magazine. Its performance is nearly identical to that of the .40 S&W.

The SAAMI Maximum Average Pressure for the .40 S&W is 35,000 P.S.I.
