Unless you plan on shooting a lot of .45 ACP for fun, there's no reason to buy the Governor. It's llght, but it's large and IMO that does nothing given what it is.
The Judge tho you get a variety of models and the Public Defenders are much smaller than the Governor and the poly models weigh less than the Governor does. The extra round is meaningless if all you're looking for is a snake gun. That said, if all this is for is snakes, any small revolver you have now can be loaded with CCI shotshells and do the same job.
For anything other than snakes, your choice of 000 Buck and .45 Colt is going to do fine if you're within the proper distances. I find the Federal 4 pellet 000 Buck to shoot the best and it's really best suited for indoors use given the short distances involved. .45 Colt is good out to 15 yards, probably more, but you'll see people saying that if you're going to shoot .45 in these .410 revolvers, you'd be better off getting a .45 Colt only revolver.
The only problem with that line of thinking is outside of Charter Arms, there aren't any small-ish frame .45 Colt double action revolvers currently made.
The one drawback to shooting .45 in the Judge (and I'll presume the Governor too) is the throats are HUGE and if you shoot lead cowboy ammo in one, it's going to lead the bore quickly and badly. So, either take up reloading and use jacketed or plated bullets or only buy jacketed/semi-jacketed .45 Colt ammo.
So, if you want a .410 revolver to add to the collection, but also be the most logical for any field work, then the Judge is the best option and a great price.
