Critical Defense .32 NAA Ammo

Ammo for the .32 NAA has been very limited, with very few companies loading for the niche cartridge. However, Hornady is expanding their Critical Defense line of ammunition to include a .32 NAA load.

The new .32 NAA ammo will feature the Hornady FTX bullet, which is a hollowpoint tipped with a polymer insert. The polymer helps to prevent hard materials from clogging up the hollowpoint cavity, and also helps the bullet expand when encountering flesh. The FTX design has proved to be both effective and popular.


Diamondback .32 NAA Conversion

If I recall correctly, I got to see a .32 NAA version of the Diamondback pistol at the 2011 Media Day at the Range.  Diamondback published this video of a barrel conversion for the DB380.

If you aren’t familiar with the .32 NAA, it is a bottle neck pistol cartridge that uses a necked-down .380 ACP case.  Generally, the .32 NAA cartridges will use the same .380 magazines, so a simple barrel change is all one needs to run the new ammo in the gun.  It works a lot like the .357 SIG/.40 S&W barrel swaps.
