Caliber/Size: The .40 S&W was developed in 1990 as a joint venture between Smith & Wesson and Winchester. Its creation was partly in response to the 1986 FBI Miami shootout and the subsequent demand for a more powerful pistol cartridge that could be used in medium-frame semi-automatic pistols.

It offers a good balance of penetration and expansion, especially with modern defensive ammunition designed to maximize its effectiveness.

Material and Construction: .40 S&W ammunition is manufactured with high-quality components, including brass casings, reliable primers, and a variety of bullet designs.

These brands ensure that shooters have access to a wide variety of .40 S&W ammunition options that offer reliability and performance.
