Thinking outside the box here, if Ruger was to make a flattop 44 Special Blackhawk, why couldn't they make a complete line of 357 mag, 41 mag, 44 Special, and 45 Colt?
I am not interested in a 44 Special but one in 45 Colt would have my interest depending on my finances and I might even go for one in 41 Mag.
