The avg gunfight lasts 3 seconds, is 3 shots, at a distance of 3 paces. I'm sure somebody has successfully defended themselves with such a sight as in the OP, but by the time Harry Homeowner gets his into play, the fight's over.

I was thinking about such a sight, but the slide has to be milled, and, it's just not as last-ditch effective (as iron sights). And a man-to-man close quarter gunfight is definitely last-ditch.

Several good shooters l know have dots on their carry guns. I asked them about the up close and fast scenario. They all said they use the sight housing as a “ ghost ring”.
