Like a lot of tools, use of a red dot depends on how the firearm will be used. Carrying/using a handgun for defense at "bad breath" distances doesn't seem like an effective use of a red dot (or even iron sights for that matter!). I put a red dot on my .22 Ruger MkIII Target because I assumed it would be easier to place a dot on my POA than aligning a rear sight with a front site to hold my POA. Worked exactly as expected in relatively relaxed slow fire target shooting. By the way, none of my other handguns, including my CC have a red dot.
