A Kimber 84M is something I'm not familiar with, I will assume it is a rifle. I suspect is it common knowledge the fitting of a rifle isn't nearly as important as the fitting of a shotgun. If a shotgun stock doesn't fit you well, you will never shot the gun well. But of course most of us that are serious shotgun shooters pay a lot more money for a shotgun than we would for any rifle we own or will ever own. I've never owned a rifle that cost over eight thousand dollars, but I owned a Beretta 687 EELL shotgun that sold new for close to that and sells for more than that now days. The most I've ever paid for a rifle was under two thousand dollars, and another six hundred for a scope. The fit was good, but I can't say it was perfect, but, it didn't make any difference, it was a rifle...
