I recently purchased an FNX-9 and I absolutely love it. I ordered some Trijicon HD sights which I'm sure will make the experience even better. I do have one concern though because I'm new to polymer pistols... How common is it for the polymer to develop the pig nose or sag? Is it inevitable? I do understand it's an easy fix, just curious.

You might see it sag if you put a heavy light/laser on the rail and do a whole lot of mag dumps back to back and really heat it up. I've gotten my poly pistols quite hot (couldn't touch the slide by the barrel without gloves) and they have never warped on their own, but I also never had any lights on them. Most lights probably won't give you an issue either.
