I was asked to make a holster for this New Model Blackhawk. Being an Old Model fan, I'm not sure what frame size this is. Is it the same as my 1969 Blackhawk .357, a bigger one like my Super Blackhawk, or like the NM Flat Tops? I can't tell at this slight angle if its flat. Can you tell by the info with the gun or just by looking at it what frame size is? And is the frame of the new Flat Top .44 Specials about the same as a Colt New Frontier? Thank you in advance for your help.
