Some time ago I bought a 5 shot, 3.5” 460S&W PC X-frame revolver. The intended use was brown bear protection.
After shooting it a bit I dropped the idea. Not beacuse it’s heavy which it is, not beacuse it’s very large which, despite a short barrel, it is. Not beacuse of the recoil which although substantial is tamable, but because of it’s tremendous blast. I don't doubt it can be effective against attacking animals but shoot it without hearing protection, and your hearing will be instantly damaged to some extent.
My local shooting club holds a casual style, high power handgun competition every other week. Folks shoot 357 Mags, 44Mags, 10mm Auto, occasional 454 Casull etc. All fairly loud, particularly on an enclosed 25m range. But when I let my 460 rip the range turned silent, and one by one the other 14 people came over to see what kind of mad boom stick I was shooting. Hearing protection is mandatory and everyone was wearing some. It is that loud.
As to the gun itself I gotta say I rather like it. It is demanding and unforgiving to shoot, any mistake and you’re not hitting what you aim at but focus on your actions and it’s ok. The trigger on mine is very good, particularly in SA mode and the rubber grip does an excellent job of taking the edge of the recoil.
Below are some standard olympic handgun targets I shot at 25m free hand. Keep in mind I’m a weak handgun shooter although I’m working on it. The gun is accurate, more so than me.

Compared to the X-frame Glock G20 feels nimble and small in hand. That’s the 3.5” version. A mate of mine has the 8.4” S&W version. With the muzzle brake it’s even louder and because of it’s weight it is difficult to hold steady at the target.
