The model 10 is a .38 Special, K frame. The model 10-6 was the prototype .357 magnum which evolved into the model 13, also a K frame.

So ..... if a model 13, K frame is capable of handling "a certain amount" of .357's, why is it in question (many times) that a model 64, being the stainless version of a model 10 is capable, "or not" of handling +P .38 Specials ..... or for that matter +P+ .38 Specials?

You can run 38 Special+P in a M10-6 with no problem. I think the FBI used mostly 38 SPL in their M13s even though they were Magnum revolvers.

"why is it in question (many times) that a model 64, being the stainless version of a model 10 is capable, "or not" of handling +P .38 Specials ..... or for that matter +P+ .38 Specials?"

There is no such question. This concern in several forms comes up again...and again ...and again. It never, ever stops. One frequent poster here calls it "Beating a Dead Horse." But it's worse than that.

Please accept my apologies.

And ......... Thanks to the forum member that PM'ed me and actually answered "The Question"!, LOL

My 64's barrel, both of them, I think, say +P right there.

Metallurgy. Maybe it's because carbon steel is stronger than stainless.
