Denial is not just a river in Egypt : As far as the original topic goes I was once denied on a NICS check. Too bad, I really wanted that revolver too.
Contacting NICS and finding out why I was denied : I actually called NICS and lucked out and found someone that would speak with me and he told me that it was because of a two decades old felony arrest.
Details : One of the most important lessons that an 18 year old can learn firsthand is that if you hang out with stupid and reckless people they're apt to drag you into their drama. At any rate one of my friends had stolen something and since I was with him (even though I was in the car in the parking lot waiting for him) they charged me as well in an attempt to get me to testify against him. I refused, hired an attorney and fought it and pled to a greatly reduced charge, paid a small fine (I think that it was $115) and quit hanging out with the guy.
To make a long story short it wasn't drug related or a crime of violence. From what I understand if the denial isn't a case of mistaken identity or from a speeding ticket mistakenly gone to warrant or something of that nature and the denial stems from an actual criminal case this can complicate things if it's one of those two. In that case it's best to speak with an attorney well versed in firearms laws
Never heard another thing about it after I pled to the reduced charge and paid that fine and I never had any problem buying guns for the next two decades. Also never had a problem when going through the background checks to get an armored car/armed guard license in Arizona for Brinks or to get my National Registry, Arizona or Texas EMT license. I even obtained a 'Set Aside' for the misdemeanor infraction (California apparently has what they call a 'Set Aside' for misdemeanors instead of an 'Expungement'). Luckily the fact that I'm obsessive compulsive had saved the day again, if I hadn't gotten that Set Aside umpteen years before then it would have taken much longer to prove to NICS that I wasn't a felon.
I guess the lady at NICS just scanned my recorded entries, saw that I had a felony arrest and didn't notice (or maybe that information just wasn't available on that specific computer) that the charge had been reduced to a misdemeanor infraction and a fine.
After lucking out initially and getting someone on the phone at NICS who looked it up on their computer and could see what caused them to deny the purchase he said to mail a letter to NICS formally contesting the denial. He said thst besides the letter to also include the denial number that they gave me at the gun store and then to also include the California Set Aside. So that's what I did as well as making sure that the letter was certified to record that the letter was sent out.
A couple of weeks after mailing the Set Aside and the letter formally contesting the denial to NICS I received a letter stating that the denial has been assigned to a specific examiner and that he'd be looking into it and giving me his contact details if I had any questions.
Conclusion : I called the examiner at NICS roughly every two to three weeks to make sure that I kept on top of it and to make sure that he'd remember who I was, but not enough to bug him. It took about 3 months to finally get a letter from them stating that I was okay to buy firearms again and that the matter was resolved. Never had another issue buying guns since then.
Unfortunately the snubbie that I wanted was gone and I never have gotten another one. Certainly not at that price. Other purchases keep getting in the way.
Since that time (2001) I've gotten a Texas CHL (I had recently moved to Texas when the denial occurred) and that means that I don't have to undergo a background check each and every time I buy a gun.
Still haven't talked to the guy that got me arrested 27 years ago.
That's how this went for me and hopefully you find this post useful. My advise is to document, document, document, to have all your ducks in a row, to store all those documents, notes and the contact details in a place where you remember where all of the documents are at and to respectfully keep contacting them to resolve the situation. Good luck.
