A Monte Carlo stock will affect that sight height for comfort and cheek fit; with my cheekbone the Williams was too low, but a std. comb buttstock cured that. Once the rear sight height suits you the front sight height may look like a gut-hook, but a ramp of the right height makes it look better.
The dangerous game rifles with that wide V express open sight on the barrel was regarded as the quickest, but that pre-dated the optics we have now.
Im inclined to think that the Red-Dot type might be better (if you have it turned on!) because of no need to align sights, just dot the danger & go, regardless of light. Any top mounted optics do ruin the look and carry of a 'classic' single shot, though, but remember what you have it along for.
Im sure somebody who has been there, done that will chime in......
and BTW, Welcome!
