Ammo is around. I have only one in my collection, because I only needed one. You can find enough to shoot and load it out of .45 dies. The shell holder is amongst the available ones, just check for fit. You aren't going to shoot PPC with this so a few rounds would do I should think...the mag will cost you and don't get cheap or it won't happen. Beautiful old gun, it's been heavily polished and re-blued though. Doesn't matter, it's yours and going no-where...nice looking piece.
