^You will love the Burris FFIII. Mine is my on Henry .22 lever action at the moment. Shot 2 squirrels with it yesterday. Next deer season Its going to be on the Marlin 336 30-30 or .35 remington. It has also been nice on my .17 HMR revolver, I shot a squirrel with it using the FFIII.
If you buy it for a handgun, try it on on a rifle and you will like it even more. The way the woods are around here, its the only thing I would want on a deer rifle.
