What is 32sw?

.

.32SW is a type of a centerfire pistol cartridge that was first introduced by Smith & Wesson in 1878. The cartridge was originally designed for the Smith & Wesson Model 1 1/2 revolver and was later used in other small and medium-sized pistols.

The .32SW cartridge is also known as .32 S&W and .32 Smith & Wesson, and it uses a round-nose lead bullet that weighs between 85 and 100 grains. It has a caliber of 0.312 inches and a case length of 0.615 inches.

The muzzle velocity of the .32SW cartridge varies depending on the bullet weight and the barrel length of the firearm. It typically ranges from 680 to 850 feet per second, with a muzzle energy of 85 to 95 foot-pounds.

The .32SW cartridge was popular in the early 20th century for self-defense and small game hunting due to its relatively low recoil and compact size. However, it has since been largely replaced by more powerful cartridges such as the .380 ACP and the 9mm.
