almost all my handguns have scopes on them. the only ones that don't are my 3 inch ruger sp101, my 14 inch 7 tcu, and my 10 inch 45/410 ( with true sights)
7 months ago my eyes where 20/200 in each eye. Now my left eye is 20/20 and my right eye is 20/25
I use to use contacts but never really liked them (don't need them anymore) because I always had trouble with them when hunting and they tend to move on me att eh worst time.
Scopes on my handguns offer me a big advantage over open sights, If I should loose a contact or dropped my glasses I could adjust the scope to be clear and still make the shot count.
I have found that my 2x leupold scopes makes things look darker in the woods in low light.
