I bought a new P89DC chambered in 9x21. It's supposed to be identical to a regular P89DC save for the barrel chambering. The price was $330, so that seemed pretty fair to me. I bought it because I like to reload odd ball cartridges. Regular 9mm reloading dies and bullets will work, so all I have to find is the cases. At any rate, I'd like to also get a regular 9mm barrel for this pistol. Would I be correct to assume that one should just drop in without it being required to be fitted? If so, anyone know where to get one cheap? It doesn't have to be new.
