I understand that processes vary state-to-state, but if this is typical, it's wrong. I would guess that the "background check" consisted of a quick search in some database(s). Of course, we all understand the limitations of databases - $hit in, $hit out. Up here, you Possession and Acquisition Licence application will go to the RCMP and there will be a
real background check. You have to provide character references and if your spouse nixes the idea, your application goes into the shredder. If you are getting separated, or there's been a recent separation, expect your application to receive added scrutiny. This process will take several weeks. Even if you changed nothing else, but had a mandated waiting period, it might save many lives. Because, the greatest number of gun deaths in the US - by a wide margin - are suicides.
