I like the size of the .32 NAA -chambered NAA semi-auto. It's the same size as their .380
Actually, I think the .32 is smaller and lighter than the .380. I looked at them recently and could really tell a difference. The .32 felt much nicer in the pocket.
North American Arms also has a .25NAA pistol. It is the .32 sized pistol with another new bottleneck cartidge. Took the .32ACP case and necked it for a .25 bullet.
Same reason as the .32 NAA, to get mucho speed from a 2.5" barrel.
