If I recall correctly, I got to see a .32 NAA version of the Diamondback pistol at the 2011 Media Day at the Range. Â 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. Â 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. Â It works a lot like the .357 SIG/.40 S&W barrel swaps.
