I used to own a 209X50 pistol an rifle barrel and was very happy with the sights they came with. I generally don't like scopes on anything that is going to be used inside 100yds.
I guess if you have trouble seeing or using open sights and have to use a scope, I would stick to something without magnification. At those short distances FOV is everything. You would also get the benefit of unlimited eye relief in an unmagnafied scope.
Just a thought. :grin:
