How old do you have to be to use a pistol at a shooting range. I turn 21 in 56 days and would like to begin collecting guns and taking them to the range. There is a range near my house that rents guns and I would like to begin getting a feel for what I like so that I can get one as soon as it is legal for me to. Do you have to be 21 to fire a gun or just own one? I live in WI if this helps anybody. Please let me know ASAP. I would like to go right after work if at all possible.
