DM-22 Cal .22 Mag
My grandfather gave my dad these guns today. He had them back when my dad was my age(im 20 and he is almost 50) so I dont know how old they are exactly. I dont know the exact names of the guns, but silver handgun had "Model DM-22 Cal .22 Mag." and "Davis Industries Chino, CA U.S.A." on it.
