In 1975 I was looking for my first revolver in 357 magnum. I was advised to stay away from the s&w model 19 because of the screws coming loose with a heavy diet of magnum loads. Now your talking about cracking or flame cutting too.
I purchased a colt Python insteadin ‘75. In ‘76 I purchased the police service six ruger. Both handguns shot and digested my stout magnum loads no problem. I have the m28 & m27 but don’t plan on shooting hot loads out of them.
