Welcome to FTE! If your username is what I think it is, then I heartily approve your choice of firearm. I had an XD 40 for a few years and really enjoyed it.
The gap is: DON'T MESS WITH IT!
They are pre-gapped. The spec is 1.32-1.42 mm, which is 0.052-0.056 in. Your plugs are pre-gapped at 0.054, so don't touch!
Not taking the time to at least check the gap to make sure it is right from factory is foolish. They make mistakes and have defects from time to time. I gap all mine to .054".

You are correct. .40 compact is my carry weapon (well one of two...)
I was installing new plugs. Had to at least check them...
