Hello,
The gun on the plywood backing is actually my gun!
The grip is indeed correctly identified as being from a steel CCF race frame. CCF made very few frames, of those made the vast majority were aluminum. The steel CCF race frames are absolutely ridiculously rare. It took me over a decade of looking to get one, and it was expensive, especially as it had to be canabalized from somebodies pride and joy "racegun". Then I sent it off to Len Savage. The CCF race frame is indeed destroyed, as far as being a gun, in the process, you are truly just cutting off the grip portion and welding that onto the M11 frame (of course it is not that simple, mag height, feeding etc.). BTW I was also able, all those years ago, to contact the former owner of CCF and ask him if he had one still laying around even if it was a defective one that he might be keeping as a memento or paper weight and he hooked me up. I got the last one!
I am currently getting ready to send an M11A1 380 off to Len for the Glock grip conversion (using that piece I got from the owner of CCF) and conversion to 9mm with tungsten bolt so I can have something much more compact. It should have a cyclic rate of around 1,000 which I am totally fine with (I've got training time on the mini-uzi and a factory Glock 18C as well).
I suppose other smiths could do it (I would try practical solutions if I didn't use Len Savage) but I went with Len Savage because he had done it before. There are I think maybe 4 or 5 total out there like mine. Not sure if they are transferables like mine.
With a CFW tungsten bolt in that thing, I would put it up against an MP5 any day for shootability or controllability and accuracy in burst (still can't compete with that closed bolt semi accuracy). I say that advisedly as someone with a fair bit of formal MP5 training and according to Anchorage Police SWAT standards (I've never been a cop but my instructor for a couple of the MP5 classes used to run APD SWAT and taught class accordingly). That was a lifetime ago!
Best wishes to everyone and a Happy New Year.
