I am contemplating purchasing either The Tasco Optima 2000 or the Docter Optic sight for my Sig P 210. A forumite was kind enough to give me info on a source for custom mounts for the Optima but I was told the Docter Optic sight with glass lenses is of much better quality and construction. Does anyone have any personal experience with either of these sights? Any feedback would be appreciated. Thanks! Dave
