A couple months ago I picked up a sweet Ruger Super Blackhawk .44 mag. Great fun to shoot. It is topped with an Aim point 2000 red dot scope. It is an accurate shooter but the scope turns off after every shot. If you unscrew the battery cover and retighten it, it comes on again. After some research, it seems to be a common issue with this model. I want to buy a new site for it, but I am new to scoped hand guns. If you can give any suggestion for a new optic, I would be appreciating it. I would like to use for whitetail hunting.
