PED - G-19RTF2 - April 2010 - - with fish gills

'PED' tells ya that the pistol is a mid to late production Model G-19.
(Not early enough in production to avoid one of those MIM extractors, though. My own MIM extractor has a #2 on it. It was very tight at first; but, after a good polishing, it loosened right up and has run flawlessly ever since.)
Just out of curiosity: Does anyone else think that Glock has machined the, 'scallops' (gills) into the slide backwards? Try grabbing the current design while your hand is slippery; I think you'll see what I mean!

By looking at the pic it would seem that if they were facing the opposite direction there would be less chance of snagging on a holster, (during drawing), or, in the case of the instructional video we are all so fond of, you Hawaiian print shirt ....
