What I carry is usually mood/job specific, but of all the handguns I own, my fave for the belt and EDC is my G23 with 9mm conversion barrel. I carry 135gr + P HP's and love it. I changed out to a ss 15lb guide rod and spring, 3.5lb Ghost trigger, and an extended slide stop for giggles. With that heavier conversion barrel, there is no, and I mean none, muzzle flip or noticeable recoil. I can stay on target for all 15 rounds. I keep one in the barrel and with 3 15rnd mags, that's a lot of heat. In the case and under the seat is the .40 barrel and a .357 barrel for it, with extra ammo for all three calibers.
*** FYI ... I just bought my first ever Sig. A P229 (no rail) in .357 Sig. Stainless steel upper and lower, factory Sig 'Nite' sights. It was an estate trade my LGS picked up. Never fired. Well, I fired it and I absolutely love it. So, it may, in short order, negate everything I just wrote above about the Glock! I have a .40 barrel coming for it from the factory, and am waiting to hear from them about a 9mm barrel for it, too. I never thought I'd gush on any of my weapons as much as I do my M&P45, but I tell you what, that Sig, in .357 Sig just moved me. It seemed the perfect mix of power, handling and feel on the hip. I may be a Sig whore now ... damnit ...
