I'm with you. I had a 640 in mind, and when I finally found one at a LGS, I had to have it. Mine was test fired 11/04/2014, so like yours, it's a very recent build.

I didn't really notice the cant on mine until I got it home and gave it a careful cleaning/inspection. It can be hard in a gun shop to turn a pistol over this way and that without sweeping people. But wow, mine is noticeable, but not *nearly* as obvious as yours.
