Back on the mainland I never carried anything bigger than my CZ P01. I quit carrying it because of the size and weight, and mostly rotated between a diamondback DB380 and a Beretta 21a. I did carry a charter arms 38 for a while, but quit because of its weight and it's failure to eject reliably. I always wanted to try out a Glock 26 and 43, or a keltec pf9 as they seem like they'd have been good for how I carried in both summer and winter. I guess I gravitate towards smaller guns, even for winter carry. If I were ever able to carry in hawaii I'd get the Glock 43. My db380 seemed to have troubles in hot weather, and I hated buying 380 ammo.
As far as big guns I don't have a lot of personal experience. My cousin carries a full size Beretta 92 year round but admits he wants something smaller. I have a friend who carries a ruger P90 with no problems, but he's got 6"and 80lbs on me.
My brother in law carries a Beretta px4, grandma carries a ruger mk1 in a purse, dad a 3" Taurus 357 in a toolbag, 4 other family members pcket-carry NAA mini revolvers

, and my little brother carries a Jennings 9mm but acts like it's a custom kimber
