For ease of carry and concealment(and weight) I carry polymer. I can't find one I am really crazy about shooting a lot, but I do want to have something that's comfortable to carry all day. All my others are steel and alloy. They're just, for me at least , much more accurate , easier to shoot well and I can shoot them for extended periods without discomfort. I realize Glocks are fine weapons, but well....THEIR BUTT UGLY!!
