That's one shiny little gun! Congrats on already being at $1200.
I'd definitely do a lot of shooting with it before you get a "Baby Glock." I love Glocks, but I really don't like the sub-compact double-stacks. The regular compact G19 is still comfortable, but the smaller ones are just as fat as the full-sized ones and not nearly as comfortable. You'd probably at least want the finger extension to get a comfortable grip. The real problem is that if you're going to carry it concealed, it's not going to fit in your pocket, and if you're going to use an IWB holster, it's still a fat gun, so you might as well get the bigger one with more capacity, longer line of sight, better grip, etc.
You may have a different opinion if you have small hands, but if I had small hands I don't think I'd like the finger grooves and thick grips of a Glock.
If you want a smaller auto for concealed carry, I'd check into the single-stack Kel-Tecs like the 38T (crazy small) and the PF-9 (very small 9mm, but still fits very comfortably in my hand).
Of course, this is getting a bit OT for the revolver forum.
Sorry!
