No. While there ARE firearms made to fire both the .45 Colt and the .410 shotshell, they were made for that purpose. Never attempt to fire ammo that a firearm was not made to fire.
No. But there are revolvers made to shoot .410 shells that also fire .45 Colt cartridges,
You can shoot 45 Long Colt or .410 shot shells with this weapon. 45 ACP rounds will not work properly.
Yes
the judge fires 45 colt which is the same as 45 long colt not to be confused with 45 acp it also fires 410 shot shells

None. While there are firearms made to shoot .45 Colt AND .410 shotshells, they are designed and made to do that. A regular .410 shotgun is NOT made to do that safely.
None. Some handguns have been made that will fire .45 Long Colt revolver rounds and .410 shotgun shells, but that does not mean that you can take any .410 shotgun and stick .45 handgun ammo in there.
Nope. The .450 is a belted cartridge.
Colt has never made a 45/410 pistol
There is a Texas based company called Bond Arms Inc. They make derringers in a variety of calibers. One is the 45 Long Colt. Due to the diameter of the 45 Long Colt and the 410 shotgun shell, the derringer will safely fire both shells. I have one. It is a blast to shoot. The quality of the firearm is excellent and it is not cheap. $400 plus.
No, is the short answer. The long answer is a little more complex. The .45 Colt and the .410 share similar base dimensions which make them interchangeable in certain firearms. Usually, however, you find .45 Colt/.410 shotgun combinations, meaning the firearm is designed to shoot .45 Colt, but will also accept .410 shot shells. The Taurus Judge, and Bond Derringer's Snake Slayer are two pistol examples. There are many variations, but the unifying factor is that these guns are designed to handle higher chamber and barrel pressures generated by the .45 Colt cartridge. The barrel of your typical .410 shotgun is very thin in comparison, and is designed to fire shotgun ammunition only. So, if the firearm is specifically designed for it, you can shoot .410 shotgun ammunition through a .45 Colt barrel. You cannot, nor should you attempt, to load a .45 Colt round into a .410 shotgun.
DON'T DO THIS UNLESS THE MAKER SAYS IT IS SAFE TO DO SO!!!!!!!!!!!!!!!!
