its a great gun, just make sure you get one at a good price. Hopefully you can find one, they sell out quickly.
make sure to mod the hell out of it, the stock trigger sucks nuts but for a few bucks, you can easily mod it to be a great shooter (I spent 40 bucks on mines and now I have no over travel, less then 1/16 inch pretravel, less then 1/8 inch total trigger travel, 2.5lb trigger, it breaks fairly nicely, and its just as reliable as stock with the firing pin engaging at least 3/4 of the sear. And this is with a 4th gen, a 3rd gen probally would have a lighter trigger pull)! Glocks are like the Honda's of guns. It will never be a Ferrari but for a few bucks you can make it pretty darn fun! Personnaly, I'd get a G34 before a 19 seeing as you can not ccw in Hawaii but that is just me. The longer sight radius and the extended slide release=better for me. Meh, what do I know.
