If your Blackhawk 45 is an original Blackhawk, then yes the 41 would have the same size frame. If you Blackhawk is the newer mid-framed style flat top Blackhawk then the 41 frame will be bigger. I am a huge fan of the 41 partially just because it is the forgotten magnum in the middle and I like off the wall stuff.I just bought a 41 magnum Blackhawk back that I owned years ago. It is a custom conversion on an old model mid-framed 357 to 41 mag by John Gallagher. I will load it with 250-265 grain cast bullets in 41 Special brass.
