Ak pistol 9mm question

[Armed-Citizen]

If I have a semi auto registered ak pistol frame, can it be used for a 9mm ak build?
The build would take Glock mags (they would be fixed).

The receivers are different.

Standard AK receiver will need to be heavily modified to make it into a blowback operated pistol calibered firearm.
^How good are you at welding?

I have some few ideas to tackle it, but my concern was can I use a 100% ak pistol receiver for a 9mm build once it’s marked as 7.62x39?
I might be just over thinking it.

i think you would need to restamp or engrave the new caliber and strike out the old caliber but you might fall under manufacturing since youre actually building a new receiver so i don’t know the legalities of that. Someone like librarian may know more. Maybe its completely legal
