NAA would not be my first choice...
I would suggest something a little larger/more traditional. Admittedly, these will probably all be heavier than the NAA, but should be more "shootable."
Several choices that I think would be more practical (some discontinued :cry: ), but perhaps more money than you had in mind:
-S&W 317 (Airweight, 8-shot, $400 used in my neck of the woods)
-S&W 63 (SS, 6-shot, 2 or 4" barrel, discontinued/can be difficult to find)
-Ruger SP101 (SS, 6-shot, 2 or 4" barrel- 2" discontinued, 4" short-shroud discontinued in favor of full-length underlug)
-Taurus 94 (blue or SS, 2 to 5" barrel, 9-shot)
All have fully adjustable sights, except the Ruger (windage-only)
All of these are bigger than the NAA, but I think they're a lot more practical and/or versatile.
Good luck!
