I am much the same, preferring the EDC X9 in 1911-pattern pistols in 9x19. That being said, the 9x19 is so seductive. It just never delivers on its promises.
I think Colt was onto something with the original Commander slide with the lightening cuts. I find it telling that Colt's original design for the Commander was in 9x19 with the slide cuts on each side of the disconnect rail so that the extractor was visible. I assume Colt had a good reason for the extra machining operations needed to remove mass from the slide. It could have been just to make a weight target (the spec for the 1949 RFQ included a 25 ounce weight limit), but I believe it was to also increase slide speed. I remember Commanders and Combat Commanders chambered in .45 ACP with the lightening cuts.
