That is why we tested for ourselves. I was surprised at how well they all did out of the subcompact guns. The biggest surprise to me was that the .357sig out performed the .40S&W.
To answer your own question ask yourself this one...Where else am I going to find a polymer framed gun with a stainless slide, an overall height of less than 4.2", an overall length of under 6.3", 10 round capacity, night sights, the reputation for toughness Glock has, that is as easy to find parts for, and is chambered in the .357sig round for under $750.
Yup, you are missing that I do not like plastic sights on a carry gun, I do not like finishes that wear easily on a carry gun, and I prefer the look/corrosive resistance of stainless.
Since I cannot find a gun that meets me criteria perfectly off the shelf I find it well worth the $750 it costs to built one that does. Plus, I had the G33 just sitting around doing nothing so that is the major part of the investment already scratched off.
It'll be really nice. 
The tennifeer finish does not wear off easily, but the black finish on the slide wears off very easily. The black is not part of the tennifer finish. The actual tennifer finish is a light grey. Also, stainless does not lend itself to scratches like any finish does. It will not scratch off and the finish can be easily repaired with some sandpaper if it does get scratched.
Pics are posted here...Fair enough.
Be sure to post pics when it's done. It'll be worth seeing.
