I took Grandpa out to shoot his gun he had never shot before. I am not sure how long he has had it but it cracked using 38 Special rounds. What is the appropriate action to take from this point? I am assuming the gun is unsafe to shoot. We didn't notice it until after getting back from the range and shooting it. he is certain he never saw it before, because all he has done with it is clean it meticulously.
