My .002 gauge won't fit in the headspace on my FA .500WE. According to FA, the only real concern regarding a very small headspace is that a gun that is not cleaned meticulously wil start to bind when it gets dirty enough. Now, if you're going to run 500 (100?) rounds through the gun in an afternoon, you may have to do some light cleaning during the course of the day.

Yep, a feeler is a feeler & .002 -.003 is fine, given the caveats already mentioned.
One of the articles recounts that Dan Wesson (himself) preferred that spec., but that they spec'd out the commercial product with a .006 gauge so the average shooter would not encounter problems.
You need to "tend to 'em" at .002!

You should also check the gap on all the cylinders, when closer than .006, they can have as much as a .002 difference on the face of the cylinder on many guns before Norwich. They were milled in the soft then hardened and the process can cause a minor distortion of the cylinder. Norwich did finish milling after hardening to insure a flat cylinder face. Some of the early manuals stated to set the gap on the tightest cylinder.
