Does anybody have any experience with Glock 33? Im thinking about trading my Glock 23 for one but would like some opinions. I love my G23 but I wouldnt mind something smaller without losing stopping power. I know there is a the option of buying a .357 barrel for my G23, but the selling point to me on the G33 is the smaller size. On a similiar note, is there any real price difference for .357 sig ammo compared to .40? Thanks Tom
