For whatever it is worth to you Elmer Keith thought very highly of his triple lock in .44 special. Off hand I do not recall for certain if this model was made in any other chamberings than .44 Special or .455 or not, it was never made n the .44 Mag. Perhaps the .38-44 but don't recall for certain when that round came out. I also don't recall if any .44 Russian's were still being made by then or not.
