Also consider that if you want a Ruger Old Army you will need a slot for a .45. To cover yourself request a slot for a .45 and a slot for a .44.
Some people will say that a slot names as a .45/.44 will do. I have been advised by a RFD that this is not the case. You need separate slots.
Seems over the top to me but I just went with the flow and have ended up with two Ruger Old Armies. Would you like one.
