Does anyone make sights for revolvers (s&w) that are more precise? I think of my old remington 510 target master rifle, it has a tiny front post with a ball on top thats maybe 3/64 wide and a deep V notch rear, I find I can really bury that ball in the notch and hit golf balls free standing at 80 yards. Now obviously thats a rifle but it makes me wonder if I could do better than the vague sights on some of my revolvers. What say yee?
