Buy whichever Glock fits your hands. I would go with 9mm, but if you want to waste your money get the .40 or .357 of your choice.
The subcompact Glocks are much less comfortable to carry, and harder to conceal, for some. The longer barrel of the full sized guns allow a skilled holster designer to use the leverage to press the butt of the gun closer to your side. Also, the smaller grip pokes me in the side, instead of riding flat against my hip. The little guns sitck out more, for me, when carried inside the waistband, than the full sized guns do causing them to print more.
I dress around my guns and have found even "service sized" weapons to be easy and comfortable to carry and conceal.
Edited to add:
One reason to buy the .40 is that there are almost new condition police tradeins all over the web for $350, with night sights and 3 magazines....
