Sig P226 9mm to 40 S&W Conversion

[trace009]

Is it possible to convert a Sig P226 9mm to a configuration that would allow me to shoot 40 S&W and 357 Sig? If so what parts would I need, about how much do you think they would cost, and where's a good place to get them?

Thanks!

I don't believe it's possible to cross from 9x19 to .40/.357. You can convert .40 to .357 and vice versa, but the 9x19 guns have a fundamentally different slide. If it were possible to convert a 9x19 pistol, you'd need a whole new top end, which would cost you so much that you might as well buy a new pistol.

Note that you can cross from .40/.357 to 9x19 via a conversion barrel.
