Good luck with that. 45lc ammo is scarce in any fashion. Better to learn how to reload. But even then it's nearly impossible as getting the components - any of them - is just as scarce.
We have loads of them, here in Germany. But are restricted to just two handguns, with some exceptions. I personally have to boxes of them but fired just a few shots from my Colt SAA. I stopped it immediately because of the excessive smoulder or fouling.
