I do not know what a Model 83 or 97 weigh and I could not find it on the website. Relatively speaking, the 83 is going to be heavier than the 97 because of the frame sizes. A large part of the answer to the rest of your post is depends.
I am a big boy and even a scoped revolver in a hip holster does not weigh me down while hunting or kicking around in the woods. My scoped revolvers are equipped with sling swivle studs and are usually carried with the sling as opposed to a holster. I happen to find the Model 83 with a 6" barrel to be absolutley fantastic for carrying on my side. Either the .454 or the .475 will give you a package that is dependable and packable; something you carry on your hip all day and place under your pillow at night.
Hope this helps.
