As an alternative to a conversion to an UZI magwell, consider getting ShockWave ZMag magazines that work great in your factory magwell. You can find out more about all the options at

His website, UZICASE.com is unfortunately no more (and the domain name is up for sale)

I bought one of their Baby Ghost uppers when I got the CFW bolt for the M11/380, put CZ Scorpion sights on it, and I bought their UZI-style folding stock to complete the package. It's a fantastic combo.
I have a similar setup on an M11/9 too.
It's so nice to have you back! I've always admired that project and your design talent. I do hope you're able to finish it and commercialize it (simply because I want one)!!
Absolutely -- and we're all grateful to Mike aka CF. I've also mentioned him in my review at
https://www.mac-11.info/review-cf.htm
so folks will always be able to see his part in developing them and bringing them to market.
As an alternative -- though not nearly as nice nor as slow -- you could go back to the first "hybrid" style bolt that CF made. Simpler machining and less tungsten, since it was tungsten only in the rear, and attached to a cut-down steel standard M11 bolt.
I own THREE of the CF-W type...
Yes, takes two. Here's an example with three barrel thread sizes:

Sam at Practical Solutions has them too, and also has a video of how to use them:
