Most of the 7.5 in. models will probably be the Bisley model. My first handgun was a 6.5 in. Blackhawk in .41 mag. and while I really liked the gun, after starting to handload it was obvious to me that with heavy loads the Bisley grip frame was much less abusive to the strong hand. The Blackhawk grip was simply taking skin off of my hand, even with leather gloves because the gun "rolls up" in recoil just like a SA Colt. The Bisley grip just comes straight back into the palm of your hand without leaving skidmarks much like a S&W N FRAME. I found a NIB 7.5 in. fluted Bisley in .41 mag., bought it and would not trade it for anything else. Loads that are abusive in my S&W M57 are easy to shoot all day in the Bisley. To really appreciate the .41 mag. you need to handload it. Even though there are many more factory loads available in .41 mag. now than there was 30 years ago, handloading gives you more choices in bullet weights and power levels.
