Hello, this is my first post on thid forum, but I have been browsing for sometime. I have an early model 60 .38 spl pinned barrel made approx 1967. I have some 158gr lswchp +P ammo that I would like to use for carry and to shoot on rare occasions. I have plenty of standard pressure 158gr loads for target practice. Is it safe to shoot +P rounds on a very limited basis in this revolver? I would consider purchasing another, but this one has the smoothest action of any j-frame I have ever owned. Thanks
