My aging eyes have a hard time getting consistent groups. I have tried ONERAGGEDHOLE sights, white paint on the front sight, white insert front sights, with the Redhawk rear sight blade, and the Merit Optical Atachment, all to no avail.

I do just fine with my scoped rifles, so I guess I will try a Weigand base and some flavor of optical/red dot sight on my MK II Target. I really hate to do that to what I think is a handsome pistol, tho... but it will beat not being to shoot at all.
Does anyone have suggestions for an economical, but reliable red dot or holographic sight? Do they even make holsters for the combination?
There is one 2X sight that is supposed to have a reasonable red dot size. Has anyone had experience with it, and is it worth a try? Or, is a standard non-magnifying sight the way to go?
Thanks.
