I like 9, 40 and 45 but I am and always have been a big fan of .40 S&WHi,
Great idea or how about a .45 twice the grains at 240 Gr.
I own a G17, G21 and G22 and all are excellent and all Gen3 but here's the breakdown.
G17 holds 17 rounds of 9mm 147Gr @ 1000fps = 326 footpounds
G22 holds 15 rounds of .40 180Gr @ 1020fps = 416 footpounds
G21 holds 13 rounds of .45 240Gr @ 800fps = 341 footpounds
Granted there are other loads but these are standards although I carry 115Gr doing 1200fps in my G17 which expands better and makes 368 footpounds, velocity is king although I do love my 1911's but I don't carry them.....actually I carry a little 380 because it's so easy and nobody ever knows I have it, most of the time I forget myself.
