You may want to reconsider the rear sight issue. I went for decades with a fixed sight aversion. When I became interested in 5 screw guns, I came across an M&P that spoke to me.
First time I took it out to shoot, I was stunned at how well I shot it. The fixed sight showed me no disadvantage at all.
