Passing Purchase Background Check and Passing Concealed Carry Check
It takes about six weeks to obtain a permit. I'd guess, if you are going to be "denied", they would catch the reason in the background check a bit earlier.
The Vegas office that processes your fingerprints, etc. is very efficient...they're not the hold-up.
Quite frankly, if you've passed the background check during a firearm purchase, there should be no problem with the permit investigation...IMHO.
Not necessarily. The purchase check is a computer search for your name, birth date and SSAN. The CCW check, in every state I know of, is an actual fingerprint check. There are records that can be found in a print check that are not in the computer data base. This is why they run the prints for CCWs. When the FBI automated things, some things were not put into the computer run NCIS. Mainly, misdemeanors before a certain date, I think it was sometime in the '80s, might even have been the early '90s, were not originally included. There were just too many of them, and someone decided they were not worth the effort at that time. This was at a time before misdemeanors of certain types, such as domestic violence, had much, if any, effect on anything. Such records WILL turn up with a print check. I believe that they are all in the computers now, but there is still a chance that something that doesn't show on the computer could show up on a print check.
Another complication, with both purchase and CCW applications, is that the requirement for having a gun is no conviction for any crime which had a maximum possible sentence of more than a year in jail. The problem here is that there are some states in which certain crimes classified as a misdemeanor DO have a maximum sentence of more than a year and while conviction records will specify the kind of offense, misdemeanor or felony and what degree, they do not specify maximum possible sentence. So if a check for either a purchase or a CCW turns up a Class A misdemeanor in another state, the state where you are applying often does not know if it was a "traditional" misdemeanor, maximum sentence a year or less, or one of those misdemeanors which can result in over a year of incarceration. This will delay everything while the state of application contacts the state where the offense occurred to find out the max sentence. Unfortunately, a lot of states do not bother to reply to such requests. Utah has a policy where they will allow the purchase or issue the CCW after some specific period of time has gone by without a response in such cases, but I don't know if all states do that. I went through this some years back when I tried to pick up a rifle I'd bought online, and my background check was put into "research" because of a 1971 conviction for trespassing, delaying things quite a while.
If you have a Class A misdemeanor somewhere in your past, and it was the traditional no more than a year in jail maximum possible sentence kind, you could run into this. There is a solution, though. Because of this problem, the FBI created a Personal Identification Number system. If you request it, they will first decide if you qualify. It seems qualifying means that you have some misdemeanor record which does not disqualify you from having firearms, but which does not clearly show that you aren't disqualified. They will then create a special, restricted access, file containing information showing that your misdemeanor does not disqualify you. They will assign it a PIN number, and you can give that PIN number on your application to purchase or your application for a CCW. The PIN file will prevent a misdemeanor from delaying your application, and NOBODY can access that file without the PIN number.
As for Clark County CCW apps, they now have a several month backlog. It seems like lots more people have been applying in the past couple years than used to be normal. Whatever county Reno is in has the same problem. If you want a Nevada CCW, applying in some different county is a good idea if that is a realistic option for you. Another thing about Clark county is that they, unlike other Nevada counties, register your guns. Depending on how you feel about that, this might be another reason to apply elsewhere even if it is inconvenient.
