Heavier loads? WHAT, are you going over to the "Skip Side"?
Never had a hangun scope. I do have a set of safety glasses that have an upper "tri-focal" though. It puts my focus at front sight distances and really helps these older (not as old as yours) eyes focus on that ole front post better!
Dale53 has shot a bunch of handguns with scopes, if he doesn't show up here soon, send him a pm. Great fellow.
