Eric Sanderson's Review of ADE Advanced Optics RD3-009 1x Reflex Red Dot Sight w/Mouting Plate 1911 Colt G/Standard Rear Sight&Picatinny Rail

The optic itself works well, but removing the factory rear sight on my pistol was much more difficult than I expected.

Once I borrowed a proper sight pusher, installation became much easier. Buyers should understand that the mounting plate installation requires a little patience and the right tools.
