Okay! If you can shoot .38 Special ammo in a gun chambered for .357 Magnum, can you shoot .45 ACP ammo in a .45 Long Colt (Taurus Judge). The reason I ask is that it seems to be very difficult to find .45 Long Colt ammo. Sorry! I do not have either .45 ACP or .45 Long Colt in my hand to compare the two. The difference may be obvious.
