I've kept mine by the bed loaded with alternating 45 colt silver tips and buck shot. I've shot mine with buck shot at steel targets. Each shell has 3 000 buck .36 70 grain at 1400 fps. I would not want to be on the other end of that.
I live on the river. I keep a snake tamer for snakes in 410 stainless short barrel shotgun.
There is a problem with your post. No factory 410 shell is shooting 1,400 fps out of a Governor, chrono them. The most highly rated are the Federal 2.5 inch loaded with four (4) 000 buck. The leave the short Governor barrel around 800 fps, while they leave a 28 inch barrel closer to the 1,400 fps you mentioned. In reality those four 70 grain bullets are making 4 holes but with a total foot pounds of energy about the same as a traditional 45 acp. About 350-375 fpe.
That said, the Governor is an aluminum gun, with about 3% scandium added for strength which makes it 29.5 ounces, much less than a model 10 which weighs about 34 ounces. And that big gun fits well inside the him pocket of my blue jeans, if i am just walking the creek behind my house. A Safariland holster is better for hiking or whatever.
I live 60 feet from a flowing creek that feeds into a major river 2 miles away, I get lots of snakes, skunks, and critters, including bobcats, coyotes etc. I only kill skunks and some snakes. I have killed 2 so far this year and relocated one large rat snake, they eat rats and mice, I like that. I actually stuck him inside a gopher hole, he will run them off for a while.
As to carrying the Governor. I use moon clips for the 45 acp. It is just like the model 25, shoots and reloads fast. With the 45 Colt it is more than accurate at 25 yards, a perfect self defense round. With 7.5 inch birdshot, you do not worry about the big rattlers continuing their movement, and a big made on will. I have killed many with 22 and 22 mag shot, it is not very effective on big ones. 38 is fine, but always carry 2 or 3 just in case one does not work or you miss.
The 410 shreds them and especially is better in water if you are fishing. I have been in the water with moccasins, they are aggressive and will come after you, there is no room for error. Unless you have been in the water with them, your opinion, is not of much value.
That said, the Governor is not a first choice unless I am intentionally going to snake areas. Then I carry two 410s, 2 buck shot and 2 45 Colt. And 45 acp on moon clips in the pocket, I carry Golden Sabre Plus P. They work very well.
I have no experience with the Judge but suspect it is much the same.
