P-239 9mm to 357 Sigbor 40S&W?
What would I have to purchase besides the barrel to change calibers in my 239 9mm? I know with a 40 all you need is the 357 barrel. But not sure about the 9mm. Thanks

I don't believe you can do that. If you look at the slides on the 9mm and .40/.357, they are quite different, as the latter is much thicker to handle the increased pressures. The 9mm barrel might work in a .40/.357 P239, though I've never tried it.
