I have recently started wondering about old Smith & Wesson durability wanted to know if it's okay to shoot these old model 10s a lot. I currently own a premodeled 10 5 screw and have put about 500 rounds through her. Not sure how old mine is either but still has the dates in the right side of the barrel. Do you guys shoot these guns often or just collect them. I really like shooting this one and she fits my hand like a glove and I even carry daily now.
