While I have a couple of NAA's, Im not real hot on them for anything but a toy. Not saying they wouldnt spoil someones afternoon, but whats the point when you can just as easily carry something thats effective.
They are not as inaccurate as you often hear though. I find they are easier to shoot well with if you dont really bother with the sights and just point shoot them.
I shot this at 5 yards, just pointing it at arms length and as fast as I could cock and shoot.
This was shot basically the same way, but from around 10 yards.
If you want to use the sights, Ive also found that they seem to work best if you use the front post for horizontal alignment, and use the base of the post and top of the frame as your vertical alignment. All of mine shoot pretty much POA that way.
Trying to use the sights like you normally would, just makes the gun shoot way low for me.
I also have a PUG version, and those Big Dots are a waste. Its faster and easier just to point shoot it, especially at the distances its likely used.
That said, all my "Baby" Glocks, the 26's, 42's and 43's, all have real sights and shoot like the full size Glocks, and to about the same distances. They arent "toys".
I figured out pretty quick with my first 42, it wasnt going to replace my 26's. I swore I wasnt going to bother with the 43's either, but so much for that.
I played with both for a while, but never saw the point to them and traded them off. The 26's are a "must-have" gun, and I wont be without at least one.
