I'm not going to bother going through all that crap, I have a good supply of handguns. But due to this "technical change" I cannot buy any more guns even though I have a valid pistol permit!
You aren't the only one who has had to go through the process in order to clear his/her name with NICS. Those I have read about doing so have reported no further problems.
I can understand your frustration, but at the same time, here in MO every single transaction goes through NICS, even for those of us with a CCW permit.
I'd personally just go though the process of appeal, get a PIN from the ATF, and be done with it- that way if you see one you'd like you don't have to think about what might have been.
