Norinco barrel swap, 9mm to 7.62

[SDoldiron]

Sorry for what will seem like an easy question. What do you need to change to go from 9mm to 7.62 x 25. Is there more than the barrel itself? I know that my Norinco 213 would have to have the spacer removed in the mag well and a different mag. Anything else? What about going from 7.62 to 9mm?
Thanks

Isn't 7.62x25 a snappier cartridge than 9mm? Are pressures ok for the change?

I believe that the Russian Takarav (sp) can be had with both barrels. How close are the Russian and Norico to being the same.
Thanks again.

You're correct they can! I forgot about that one. Also I have a PPsH barrel in 9mm. Only change we made on that was the barrel. I guess it would be OK after all.
