I have giant hands but love the 19. Note that the 17 is the only one that you can get in 9mm where the barrel does not stick out of the slide due to our legal requirements. There are also little 26s available if you really love small frames, but they are pricey for what they are and they look ridiculous with the aftermarket barrels. In order of biggest to smallest you have the models 34, 17, 19, 26, and the newest 43.
