32 NAA

The 32 NAA (which stands for “North American Arms”) never achieved mainstream popularity following its introduction in 2002. The cartridge features a 380 ACP case that is necked down to seat a .32 cal bullet, and was developed to offer improved ballistic performance over the 32 Auto. The 32 NAA’s bottleneck case is just one reason why it is totally incompatible with other .32 cal firearms including 32 Auto, 327 Federal Magnum, 32 H&R Magnum, 32 S&W and 32 S&W Long.
