I tried asking SA this, but they kind of gave me a lawyered up response saying it might be possible, but they advise against doing it.
I'm wanting to get an extra barrel and some new mags for my 10mm XDM so that I can shoot 357 Sig through it. I know you can do that with other caliber XDMs, but I believe the 10mm XDM is a different frame size than the 9mm/40/357 XDMs. Does anyone know if the barrels and magazines are interchangeable?
