That is a cool old pistol. DO NOT SHOOT 38 SUPER IN IT. You will end up with a headache. I have an old post of a model 1900 on the forum that will show you what happens after a while. My sisters boyfriend is from Michoacan, I know how they love their Supers down there. I bet the original owner was blasting away with them.
