I am unaware of any revolver in the size class of the NAA since the Freedom Arms is no longer made, much less a more reliable one. Yes, they're very reliable as long as you refresh the ammo in 'em every week or two if you're carrying 'em constantly in summer. That's the trick. Pocket moisture (sweat) will infiltrate a rimfire round. I think the magnum might be less susceptible to this since it does not use a heal seated bullet, crimps over like a normal center fire round. But, I don't have a mag model.
These guns can be useful to 15 yards in my experience. I can hit center mass quite easily from 50 feet, but with slow, aimed fire. They don't point shoot for squat and the sights are tiny, sight radius is short and they're slow to acquire. I really wouldn't wanna get into a gunfight with one, but it could save your bacon if you need something and just can't carry bigger. I have mine in a holster grip which flips open like a lock blade knife and gives me a full grip which helps immensely.
There are very few times that I must carry a mini as a primary, but there's no substitute for one when tiny is needed. One neat use for it is when I'm wade fishing. I clip it to the top of and inside my T shirt. I would not be able to carry anything else in that situation without it being submerged in salt water.
These little guns are very well made and very reliable. They actually shoot well, but ammo picky and one must practice to understand how to hit with 'em. Some folks just can't figure it out, some better shooters can. They're not expensive and are of very high quality. I'd suggest buying one and seeing for yourself. Don't give up on it. Work with different loads, find one that hits near POA or if you have to, and I did, file the front site down a bit to match the POI of the load. Once you have this little thing set up, it actually CAN shoot. .22 LR is pretty pathetic for penetration, of course, and tiny, but hey, it's better'n nothing. The .22 mag offers better ballistics. The frame of the gun isn't that much bigger, but yeah, they're loud. I've got a .22LR and a super companion which is worthy of a whole nuther subject, but I consider the best option yet as reloads are fast (spare cylinder) and ballistics are slightly superior to the mag using bullseye as a propellant with the 30 grain conicals from NAA. With it or the .22 mag with solids, I'm a little more confident in penetration potential than the .22LR, but the LR is the more compact frame. I want to get a magnum version eventually just because. Both my NAAs wear the holster grip, I'm sold on it for my uses. You could clip it inside the waste band of a pair of bicycle shorts and no one would even know what it was.
