What he said. I have both and I carry the 19 everyday in a tucked in dress shirt with an occasional tie. A fantastic instructor I know puts it this way, "carry as big a gun as you can". Kep the 26 unless you want to trade it to me for something and get the 19.
I got a FDE 19 yesterday, love the way it feels. I see myself carrying it just as much as I will 26. Would like to either find a FDE 17 to trade for my black 17 or just trade the FDE 19 and 26 I got for those 2 in black so whole family matches. I think the 19 was the best purchase I have ever made.
