I have a G27 that I carry IWB, pocket, as well as in an Itac retention holster. It's a bit of a bear to carry IWB & pocket because it's a double stack. However, my Taurus TCP (.380) is noticeably harder to shoot. The G27 is not much worse than a G23. I think the double spring really improved the gen 4 over the gen 3. Rent one & try it.
