Ah, got it. I googled around and found a PDF by the Baron people that lists the final gravity of this beer as 1.010 and 1.016. So 1.019 isn't that far off, but I would definitely give it a few more days and to continue checking it to be sure it doesn't drop anymore.
Did the directions that came with this list a recommended fermentation temp? It is odd that they would call it a lager but then have you ferment at ale temps...
