45/70 is the only caliber to get that handgun in.
Other calibers can be found in other handguns. The 45/70 caliber is the very reason to buy that particular firearm.
You can also pay a little extra, and they will include a .450-Marlin cylinder that can be swapped in and out. The .450-Marlin is actually the Magnum version of the 45/70, sort of like the .357-Magnum is to the .38-Special.
