My 1911 wore Tijicon Tritium night sights for a few decades until they finally got dim and went out. Getting into the 21st century, I put a Tijicon RMR on that .45 and holy smokes, what a difference in accuracy! My eyes probably haven't gotten any better over the years either, but put that red dot on the target and that is where the bullet goes. No focusing on a back and front sight and then the target. Everything is in the same plane. The RMR has a smaller sight window and lower profile than the newer SRO and if the larger size of the SRO isn't a concern to you, that larger window makes seeing that red dot easier. That SRO would be my choice for a home defense low light 1911.
