Hey guys, I recently was given a revolver that belonged to my grandpa. He got it from someone many years ago in exchange for some demolition, and never fired it. It's a double action revolver, looks like .357/.38, I can't tell the model because the barrel looks to have been replaced with a heavy target barrel. I'm actually not even sure this is possible, but the I know nothing about these things. I actually want to know if it can be changed again, as the current barrel is really rusty. Where can I get it? How can it be done? Could the heavy barrel have been a factory option? I'll try to get some more info from it and share it with you guys after a good inspection. Maybe some pics too...
