The .32 NAA (North American Arms) is a firearm cartridge that was developed by North American Arms and Cor-Bon in the early 2000s. It is essentially a .380 ACP case necked down to accept a .32 caliber bullet. The purpose behind this design was to enhance the ballistic performance of the .32 caliber round, offering greater velocity and energy compared to traditional .32 ACP cartridges.
Typical specifications of the .32 NAA include a bullet weight of around 60 to 71 grains, with muzzle velocities generally ranging from 1,200 to 1,450 feet per second, depending on the load. The design aims to deliver improved penetration and stopping power, making it a viable option for self-defense in compact and lightweight firearms.
The .32 NAA is primarily used in small, concealable handguns suitable for personal defense. Its enhanced performance makes it a more potent option than the .32 ACP while maintaining manageable recoil.
Overall, while not as widely adopted as more common calibers, the .32 NAA offers a specialized option for those seeking an effective self-defense cartridge in a relatively small package.
