After reading all of the responses I am very surprised that no one has spoken up regarding the virtues of 45 Colt in this pairing. The 45 Colt is very versatile and with a Ruger Blackhawk or similar, it can be loaded mild to wild with ballistics rivaling or bettering the 44. The combination of Blackhawk and something like a Rossi 92 can be had for a modest investment and cover everything from paper punching to CAS to hunting just about anything in North America.
My 2 cents....
