I can relate to your situation and it seems that in the process of losing our younger eyesight, we go through stages. On my M/L's, the open sights and peep sights, still work well for me and know that I would never put a RedDot on any of my SideLocks Now then, on most handguns I'm not so good with open sights so have chosen to mount the fiber optics and that works well for me but
RedDots, give me the best performance. Kind of depends on the type of shooting I'm doing and "what" I'm shooting. If you are still getting along with your fiber optics, so be it. I have a couple of handguns with fibers optics solely on the front and that works. .....
RedDots and Fiber optics, look like crap, on SA Colts ......
Be Safe !!!
