This happen to me, but was a little different and I might understand why. I was originally convicted of something I didnt do, later on I was cleared. I had to go thought hell and hi water to fix everything ( well not really but it was a pain ). Either way after that I always got delay, but I would never put my SS, so I got the great idea to put my SS down on the last gun i bought. Well guess what there was a denial. So my process is the one that is a easy fix some times, you just email the nics with the proper doc's that show you are good to go. Since this is on my record, even tho it shows dismissed it doesnt matter, I can get denial every time unless I get the pin nics puts out. So that is what I am done right now as I type this out. I had bought 3 other firearms before this and have a ccp of my state, just a pain in the ass really.
