I put too much magnification on mine, while it is great for accuracy the field of view is very limited and takes longer to get on target than is needed, go somewhere you can try different ones on a frame. I have no idea on a red dot.
I have a Burris FF3 on a Browning Buckmark that I absolutely love. You can change the intensity (size) of the dot, makes it really easy to stay on small targets and much lighter than a scope.
