I got a G17 Dragonfly for duty use. The total weight of the unloaded pistol is 22 ounces. According to GLock, a stock G17 weight 25 ounces, so they removed quite a bit of weight from the slide. I've only shot 60 rounds through it so far for qualification, but I was extremely impressed. It's no Infinity, but it's shoots really flat and fast. The lightened slide, combined with a sipping and mag well, really let you lock into the pistol.
