Today the cartridge has an increased popularity in the United States due to modern compact concealed carry pistols chambered for it, such as the Kel-Tec P-32, Beretta Tomcat, Seecamp LWS 32 and North American Arms Guardian .32. This increase in popularity has led many ammunition manufacturers to develop new loads for the cartridge to increase performance. However, these subcompact guns typically have barrel lengths around 2.5". The traditional steel guns chambered for .32 ACP have barrel lengths around 3.5". Different barrel lengths can have a significant effect on bullet performance with longer barrels providing higher muzzle velocity and energy. For example, a Cor-Bon 60 grain .32 ACP JHP has 130 foot pounds of energy when fired out of a 2.5" barrel and 165 foot pounds of energy when fired out of a 3.5" barrel. The shorter barrel length can also reduce the range of a bullet.
