It was originally created for use in a smaller and lighter model of their Guardian pistol. Despite popular belief, the 25 NAA cartridge is not based on the 32 ACP case. It is based on a rimless version of the .32 ACP case, shortened to .745" and necked down to accept .251-inch diameter (.25 ACP) bullets. The 32 ACP case, at only .680" long is too short for use in 25 NAA production. History and design The cartridge was originally conceived of and prototyped by gunwriter J.B. Wood, and called the "25/32 JBW". North American Arms and Cor-Bon Ammunition then further developed the cartridge, and the NAA Guardian .25 NAA pistol combination for production in consultation with Ed Sanow. Introduction The finalized cartridge and pistol were introduced at the 2004 SHOT Show.25NAA Press Release North American Arms http://www.naaminis.com/25NAArel.html 2018-11-26 dead https://web.archive.org/web/20110722041555/http://www.naaminis.com/25NAArel.html 2011-07-22 It followed the successful introduction of two other commercial bottleneck handgun cartridges, the .357 SIG in 1994 (which necked a .40 S&W case down to accept .355 caliber bullets); and the .400 Corbon in 1996 (which necked a .45 ACP case down to accept .40 caliber bullets). Performance According to NAA's website, the .25 NAA's 35 gr bullets travel faster (1,200 f.p.s.) and hit harder (20% more energy on average) than larger, .32 ACP caliber, bullets.
