"For many years, there have been dire warnings about not shooting .38 Special in those guns put out by folks who apparently were not aware that Colt actually made the later ones to take that round."
The big question is, though, did Colt heat treat the cylinders when they started officially chambering the guns in .38 Special?
I don't believe the Army-Navy models had heat treated cylinders.
