It will vary with the maker of the bull barrel.
a 1911 barrel, by itself is not illegal, except maybe in a school.....................

Barrel diameter
Do a search for Jarvis. They make a bull barrel for the $597, it runs $198 in either blued or stainless.
A heavier (bull) barrel is stiffer than a light barrel. It does not vibrate during firing as a light barrel will. Combined with a steadier aim due to the increased weight, the combination produces greater accuracy.
You will probably have to contact a barrel maker.
A PMI razzor barrel (spyder thread) will fit your barrel needs. You know it will fit if it is "spyder" threaded.
Barrels are to small to fit any one horse into it. So no horses can fit into a barrel.
