balsrc= Cartridges of the World "Cartridges of the World 11th Edition", Book by Frank C. Barnes, Edited by Stan Skinner, Gun Digest Books, 2006, ISBN 0-89689-297-2 p.291]The .32NAA is a cartridge/firearm 'system' designed and developed by the partnership of North American Arms and
Cor-bon Ammunition. The cartridge is based on a.380 ACP case, which is necked-down to hold a 32 cal. bullet. The benefit is a remarkable gain in ballistic performance.History and Design
The .32NAA is the most recent of a line of commercial bottleneck handgun cartridges that began with the
.357 SIG in 1994 (necking a.40 S&W case down to a .355 bullet); followed by the.400 Corbon in 1996 (necking a.45 ACP case down to hold a .40 cal. bullet); and then the.25 NAA in 1999 (necking a.32 ACP case down to hold a .25 cal. bullet).Performance
The cartridge delivers in excess of 1222 f.p.s. velocity to a 60 grain proprietary bullet from Hornady. This generates convert|199|ft.lbf|N.m|abbr=on of energy from the 2.5" Guardian barrel (1453 f.p.s. & convert|287|ft.lbf|N.m|abbr=on from a 4" test barrel).
According to industry expert Ed Sanow, the 32NAA: produces more velocity, more energy and more stopping power than any conventional jacketed lead hollow point (JHP) 32 ACP, 380 ACP or 380 ACP (+P) with 15% less recoil (Power Factor) than the (+P); penetrates 8.3" of gelatin after passing through four (4) layers of denim, expanding to a .55" mushroom with a retained weight of 100%; and has a Fuller Index of 62% One-Shot Stops (compared to the 380 ACP Federal 90gr. Hydra-Shok (53%)).
Handguns
The .32NAA Guardian pistol is designed around this cartridge. This gun is almost identical to .380 ACP Guardian, different only in the chamber and the size of the bore. The cartridge is manufactured by Cor-Bon, a well-recognized industry leader in the development of high-performance ammunition.
