My buddy just gave me a really old H&R Model 732 revolver. It's in real rough shape and his brother had painted it for some stupid reason. Oh well. I know that it shoots because he shot it before he gave it to me. It's a slick little gun but the cylinder doesn't rotate after each shot and you have to do it manually. I want to fix it so that the cylinder rotates but this is my first revolver and I don't even know where to start. Thank You and I hope this is in the right section.
