I am guessing that the ones for the .44/.45 pistol will work just fine. I honestly don't know if any of the local shops have any of them on the shelf or not. If not, I am thinking TOW has them. I know that is something I wanted to put on my order when I got round balls for my .31 Remington C &B pistol but seems I had a brain fart when placing my order and that item got left off.
Glad the scope cap business has been good this year, I have money left now to get new goodies to play with.
