No problem with getting acceptable accuracy from my LCP, Taurus 22Poly, or Kel-Tec P32. But I haven't mastered the are of accuratly shooting my NAA 22 Short Mini Revolver.
There is no art to the NAA mini revolver, it's all based on luck and knowing how to pull the trigger. I've shot what has to be close to 1000 total rounds thru the two NAA's I have, so I'm pretty skilled with knowing where the trigger breaks, but even then with the little one I have, it's a struggle to hit anything 10 yards away. There's been times where I've shot the thing extremely well, then the next time I'm way off.
It could be the ammo, the lack of rifling means that some bullets and ammo will not like these guns all and some will do better, but still shoot poorly and I say this not having done extensive testing off a rest because... there's nothing to rest on.
The sights have the biggest impact on accurate with these guns and given how the grips are, to get a good picture, you have to angle your wrist down in an uncomfortable position or you have to change your grip.
Personally, I want to do neither and the NAA is one gun that I feel needs a laser and unfortunately LaserLyte stopped making the laser grips for the NAA mini revolvers.
All that said, if I had the choice, if someone today would reproduce the old H&R Young America revolvers, maybe make some updates to the design, I would rather have one of those. At 7oz you get 7 shots of .22 or 5 shots of .32 S&W and that is more than enough considering the improvement over what the NAA revolvers are.
