Hi folks, I have a Ruger MK3 Hunter with a 6.9" barrel and a Burris FF red dot. I want to change to a pistol scope but I am unsure which one to pick. There are quite a few 2x fixed magnification available and a few 2x6 or 2x7. Most important is eye-relief, but then I am wondering ... I'd like the option to "zoom in" but it comes at a price: longer scope, heavier weight, lenses that comes lose over time, etc. Have been looking at BSA, UTG, Simmons, Bushnells, etc. For my rifles I have Leupolds, but I am not willing to spend that kind of money for this pistol right now. My anticipated range is 20-100 yds. With rifles I am typically at 4x when shooting 100 yds, but that doesn't mean I could not do with 2x. Have not tried it, to be honest. Any experienced pistol scope shooters' advice? Thanks much.
