.40 S&W ammo for sale is a rimless cartridge jointly created by both Winchester and Smith & Wesson. The .40 S&W was specifically developed as a law enforcement cartridge that was supposed to mimic the FBI’s 10mm cartridge. The cartridge uses .40-inch diameter bullets and has a 1.25 ml cartridge case capacity.

The .40 S&W cartridge was introduced on January 17, 1990 alongside the new Smith & Wesson Model 4006 pistol. The cartridge was a result of a collaboration between Smith & Wesson, Winchester and the FBI following a 1986 shootout in Miami, in which the current FBI’s revolvers were found to be incapable of competing with automatic weapons.

During this time, the FBI carried out a series of practical tests that consisted of eight test events which represented various scenarios that agents would likely encounter. These tests resulted in the creation of a 10mm cartridge known as the 40 S&W. Although the 40 S&W ammo currently for sale is only 1mm above 9mm, many say that it is far greater than the 9mm Parabellum, and in fact, is the ideal law enforcement and defensive cartridge.

The energy of the typical .40 S&W ammunition on sale today generates 350 to 500 foot-pounds of energy, exceeding the pressure of both the .45 ACP and 9×19mm Parabellum cartridges. Although it's is very popular amongst U.S. law enforcement and American gun owners, it has never been adopted by a notable amount of military forces.

The overall cartridge and case length of 40 S&W ammo for sale is shortened, but the other dimensions are identical to that of the 10mm Auto. Although there are some disadvantages to the 40 S&W ammo for sale today, the cartridge has been relatively successful in the United States. While it has almost identical accuracy to that of the 9mm and 10 mm Auto, it has a small energy advantage over the Parabellum, with a lighter recoil than that of the 10 mm Auto cartridge. With the right JHP bullets, .40 S&W ammo for sale has a substantial stopping power, and it can induce hydrostatic shock in man-sized living targets.

.40 S&W ammo is perhaps one of the most capable types of handgun ammunition in the world, specifically designed for and by the FBI. Although this cartridge was originally created for American law enforcement agencies, it is now available to the public, and it makes an excellent defensive cartridge in most situations.
