This one is from 1979. A little rough when I picked it up but….local gun shop had it and one of the employees was looking it over and pulled the cylinder. I picked it up and looked through the chambers. Well well, it's a 45 ACP instead of 45 Colt. For $450 out the door, it followed me home. I've loaded 200 grain round flat points and this morning, switched to 185 grain semi wad cutters.
