I was listening to an episode of reload radio today and they said to change calibers in a G 22 all you have to do was change barrels. Is this true for particular calibers?
I have a Glock 22 and it came with a ported wolfe 9mm barrell and yes its just a drop in and go, you can use the 22 mags for the 9mm but they are sloppy, better off to get a 17 mag than no fuss at all,
For your G22 just get a 40-9 conversion barrel. You can use the .40 mags but the G17 mags would be better.
