Would this cause me to fail a NICS check? I have firearms in the home that belong to my elderly father for quite some time now and feel safe and confident that I am able to own firearms without being a danger to myself.
Give it a try. Explain what you want to a local gun dealer, or start the process and then back out. (might upset a dealer doing that, but maybe you don't what anyone to know what you are trying to find out(have an empty check book that day))?
It is better to know where you stand prior to having a strong desire to make a purchase or the plan to go on a hunt and a new rifle/shotgun would be needed.
Now the CC application or handgun purchasing permit might dig deeper, as it dose in MN. We have to sign a release that gives the agency access to mental health records. That is over and above NICS checks IMHO.
