I have both scope sights and Red Dots on my handguns. After a couple of years seriously shooting my Red Dots, that is now my favorite optical sight.
I prefer the 30mm size (larger field of view than the 1" models and not so top heavy as the larger sizes).
I have a half dozen Simmons Red Dots and am quite partial to them. They are only to be used on .44 Magnum or lighter recoiling handguns. For the "heavy hitters" (.454 Casull and above) it is recommended that you use a 30 mm Ultra Dot. I like the four reticule model. I use the crosshairs for shooting groups off the bench and the large dot for hunting and offhand target use.
Most big game are seen at dawn and dusk. This is the area where the Red Dot sights RULE. They also work quite well in bright light.
One of the big advantages of Red Dot sights is they are more compact than scope sights.
