I have seen one other of these and was talked about on one of the Facebook pages. From what I remember, these were made by a European company/gunsmith out of an actual short rail. It would have been an extensive project for sure, I’d love to see the inside of that thing. Looks to me like it doesn’t have a bushing anymore, and the grip looks like a cut down full size vs. the properly proportioned compact grips. The mags would have had to be modified as well. That’s not much help, I’ll see if I can find the thread I’m referring too.
