Bert & several other members make a good argument about maturity and ability to pull the trigger if need be, these are questions that I cannot answer.
I do know that there are more bullets in a revolver than the times the father has gone out shooting, and still has three partial boxes of ammo, one for each caliber of firearm he owns 22lr. 45ACP and 32ACP., maybe less than half of that time the daughter has been along. Other than boyfriends taking her out plinking, I would assume that is her firearms experience.
And as far as moving, where she lives is in the less wealthy parts of mountain towns along the I-70 corridor and is always hard pressed for accommodations due to employment opportunities.
