Bill Ruger made a near duplicate of the 1873 Colt Peacemaker in 1955 that was chambered in 45 Long Colt. He then tried chambering his Blackhawk in 44 Magnum and they’d blow up.
So Ruger increased the size of his pistol, beefing up the frame and increasing the cylinder size, which we still call the Ruger Super Blackhawk.
Until 1973 the Blackhawk was on a smaller, Colt sized frame and the Super Blackhawk a larger one.
In 1973, Ruger went over to one large magnum sized frame for both the regular and 44 Mag Super Black Hawk.
In 2009, Ruger announced the 44 Special Flattop which was made on the New Model Vaquero frame, which is Colt sized.
Only a 44 Special can safely launch 240-50 grain flat nose lead cast Keith bullets at 1,200 feet per second, using reloads of 2400 powder. The 44 Mag case is 1/10” longer. Four more grains of 2400 only gain less than 200 feet per second and it requires a larger frame and cylinder than a 1873 Colt sized revolver, or it blows it up. Plus 1,200 fps is about the limit for lead bullets. More and it needs a jacket or bullet cup, and accuracy suffers.
The 44 Special case, is the most accurate handgun cartridge in history. It’s less than one MOA in well made factory Rugers.
The 1873 style frame is by far the easiest style handgun to hit with. It dominates cowboy action shooting for that reason.
The genuine Colt 1873, while a beautiful work of art, cannot compare with the reliability of the modern Ruger. The Ruger is a 1955 design and the Colt from 1873.
