You will also likely find that if you actually were using hot dipped galvanized finish nails that your air nails likely wont have the same holding power because they are smooth (even if they are glue coated). We use to always set door jambs with hot dipped galvy naiils not for the corrosion resistance but because the rough texture on the nail from the hot dip would really grab the jamb and the framing allowing you to leave the finish nail very proud initially and you could use a bar to slide the jamb in and out before shimming. The jamb would stay put on the rough surface of the nail where as it would slide all around on a bright finish nail. If you had to pull one of these nails it was a chore.
You can pull a shot finish nail (regardless of the gauge) out of all but the most stubborn of woods very easily.
