I don't run dots on my guns as they're a failure point where there doesn't need to be one. Fog, battery, damage, remedial action, and in increases the possibilities for stoppages. They also take longer for me to acquire to the point it doesn't make any sense for me to run one. I'm much faster and more comfortable with irons. I also don't want a cutout for something I'll never use, and it's just the possibility of losing that plate or something dumb happening.
