Zulch, yes, I still have the Open Top I wrote about above. I did add a shorter, 5.5" barrel that coincidentally is marked "44 Colt." That was what was available at the time.
I also use 44 Russian cartridges ( my reloads with, again, Starline brass) in this gun. I never did go through with an early consideration to get a 44 finish reamer and deepen the chambers. It is too easy for me to feed the gun 44 Colt and 44 russian cartridges.
