Well, I contacted a gunsmith in Tampa about making this modification. Sent him an email with lots of pictures. Says to bring it over and he will look at it to give me a verdict. Says he has every machine tool needed to do it.
This place does excellent work, so I can trust him.
Now another question. If can does make it fully collapsable, it would be legal, right? The ban is history.
What if they put the ban back into effect some day. I guess I will have to convert in back or maybe it would be grandfathered in?
