Smith & Wesson and Winchester introduced the .40 S&W in 1990, replacing the 10mm cartridge used for a short time by the FBI. The 10mm had proven to be too difficult for many agents to control when firing, due to the combination of harsh recoil and large grip size. In response, the FBI searched for a cartridge with less recoil that fit in existing 9mm frames, and could deliver the amount of penetration required by the FBI. The .40 S&W met these requirements, was adopted by the FBI, and was enthusiastically embraced by the law enforcement community. Civilians soon followed, offering their own endorsement of the caliber.
A strong feature of this ammunition is that it is a "middle ground cartridge," yet it avoids being a compromise. It strikes the right balance between muzzle energies and magazine capacity, and has been approved by exhaustive testing on the part of the FBI and many other agencies – resulting in widespread adoption of it among the police community. It is also worth noting that the the caliber has been adopted by the U.S. Coast Guard as its primary issue sidearm.
The caliber is popular with civilians for many reasons. A wide variety of options exist for bullet weight and bullet design, and if a manufacturer produces a new line of self-defense firearms, they are sure to offer it in .40 caliber. Civilians appreciate the same benefits of the caliber that made it so popular with law enforcement: magazine capacity, muzzle energy and limited recoil. The cartridge is popular for home defense and concealed carry, as seen in the number of pistols chambered in it of compact and sub-compact size. Defensive ammunition is offered by several manufacturers including Federal, Hornady and Magtech – just to name a few.
