My Presbyopia is real bad now so I've been experimenting with Red Dot sights and scopes on a few handguns. Scopes don't seem to do much for me, too narrow an exit pupil on my Leupold, and a cheapie was worse.
So far IMHO the Red Dots I've tried all have too big a dot for precise aiming, but are fast to get on target. Got a Tasco ProPoint (your BSA pretty much looks the same) on our Beretta Neos. My wife loves it and its helped improve her shooting because it takes front/rear sight alignment out of the equation and lets her concentrate on timing the trigger break for when the dot is on the bullseye.
