i've also been involuntarily hospitalized, twice for me. afterwards the gun store guy said i could try & lie on my app to see what happens, but he didn't know what would. it's a federal law to not sell firearms to any1 w an involuntary hospitalization, so i didn't wanna take the risk of getting arrested & being stuck in a cell on top of everything else, lol. could always try it though.
from what ik, it's like the other poster said. u have to go through an arduous legal process to restore ur gun rights, which i couldn't afford. had to swallow the pill & prepare for a diff method ://
