I may purchase a 44 Flattop that has had the safety conversion; and I would like to change it back to "pre safety conversion" using an OM hammer/trigger that I have stashed (from an OM 45 Colt Blackhawk). Just want to be sure they will fit in an old Flattop 44. Will the OM parts from a large frame 45 work to convert that OM 44 Flattop...? If so, any surprises to be aware of...? THANKS, Johnnu2
