I can highly recommend a Bushnell Elite 2-6X handgun scope. You have the choice of lower magnification when desired for field of view and higher magnification when needed for accuracy testing. The scope adjustments are accurate and repeatable and can be done with only your fingers. Eye relief is one of the best among handgun scopes and does not change between 2X and 6X. This scope would have to be found used, Bushnell no longer offers it. But for my dollar, it's the perfect handgun scope.
