a DAO revolver ..... not in a safe and within easy reach. Impress upon them a loaded firearm is not a threat to them, with of course, the exception, if they are on the receiving end of things.
I know people like them and have tried to help them through the process... alas, to no avail.
There is just so much we can do, if the party refuses to heed our advise.... That said, we must let them proceed without our help or advice since it is obvious they are too afraid to take their personal safety into their own hands and take advantage of your input.
Let it go my friend and be aware that you did all you could to help them.
