My daughter is getting ready to move out into her own apartment and needs a self defense weapon. She and I took hunters safety when she was 12 and I bought her a .22 rifle at the time. When she turned 18 and moved out the first time I gave it to her. Now she is moving out for the second time and although the rifle will be better than nothing for protection, I want her to get something else. So, how old do you have to be to own or possess a firearm in Wisconsin?
