At 64 my eyes aren't as good as they used to be. But I feel I can still make hits with a handgun out to 15-20 yards to do well enough. On rifles I expect better accuracy than I can get from a dot sight. Or iron sights at this point. I see no downsides to a conventional scope on a rifle unless it has too much magnification. The only downside I see on a handgun is limiting how it is carried. For range use I'd have no problem with one. And as said want to try one eventually.
