I kind of doubt they tout it as a "must have" in order to shoot .45 Colt in their revolver, however. Maybe "nice to have", but certainly not a "must have".

One of the pitfalls of shooting .38 or .44 Special in the .357 or .44 mag, or .45 Colt in the .454 Casull, is the shorter case of the lower powered round. All revolver (or pistol, or rifle) rounds tend to cake the hardest fouling right in front of the mouth of the case. After a few cylinders worth, the longer rounds will no longer chamber until that fouling is removed. Not a big deal if you have cleaning equipment with you. Alternatively, not a big deal if you have two cylinders, one for the long round and one for the short. The cleaning equipment is a bit cheaper, though.

this occurs alot on lever actions using 38 in a .357 lever and .44 special on a .44 mag lever.
