Chris Costa has a decent 25 min video highlighting the pros and cons of red dots on pistols. He makes some points that may be of use to you. Such issues like moisture obscuring the emitter or the glass. For LE or military he brings up the use of NODs and red dots. The pros do out weigh the cons. One aspect that I didn’t consider is age and eyesight. Red Dots can be easier for older shooters. Costa talks about certain types of corrective lenses that may cause a shooter to spend more time getting their sight picture but a Red Dot would help to speed that process up.
