I have a Burris fast Fire II on my Ruger .22/.45. Its great indoors but in bright sunlight the dot is hard to pick up sometimes, especially for shooters who have never used one.
I may replace it with Aimpoint or similar red dot. Maybe a C-More, lots of competition shooters use them...
as far as magnification. I would get a variable and a good set of shooting sticks. scoped handguns are hard to hold steady.
