It depends on the distance you want to hunt. I think most Ruger's are limited to 75 or 100 yards. The Leupold Gilmore is a dandy. The red dot is really nice. I have one on my S&W Stealth Hunter. It works great to 100 yards with a 2 minute dot. If you want a variable I like the Burris. The Burris seems to have the best eye relief. At least it does for me. Tom.
