Smith Compatibility

Can you tell me if a 586 barrel will work on a 19-3 frame?
I only ask because I need to put another barrel on my 19, and I am partial to the full underlug.
Thanks, Justin

I'll bet they will, same frame size just a longer cylinder. the 'K' frame uses the same barrel shank & thread all the way from the M&P to the latest ones.

But would the extrator rod housing be compatible with the 19 extractor rod?
Thanks, Justin

a 19-3 was a pinned barrel, the 586 was not, press-fit IIRC.

you might run into a prob there, not sure.

I doubt it. The 586 is a"L" frame and the 19 is a "K" frame. S&W made the "L" frames bigger as a steady diet of full house 357,s were hurting the 19,s barrels.
