This news hit the web today - the blog article below gives all the details and some great pics. The fit/finish is really very good. (Edit: reading carefully they say it was post-print cleaned up/polished. I'd really like to see a pre-polishing pic).
It was only a matter of time. Perhaps in another 15 years or so when you go to a gun store you might just have them print out the design you picked online- no hassles with inventory/shipping from the factory etc. Same thing for replacement parts too.
