FWIW, Apex's new FSS trigger kit comes with two trigger return springs now, the 2nd spring being heavier to keep the pull above 5lb. Just throwing that one out there as another option for ya. If I carried a compact instead of a Shield, that's the kit I'd go for. I have the FSS in my Pro and everyone who has shot it really likes it. Add the heavier trigger pull and I think you'd have the best of both worlds, IMO.
