As I see things the Missouri law will not satisfy the Federal restoration. In US V Caron the Supreme Court said
"In sum, Massachusetts treats petitioner as too dangerous to trust with handguns, though it accords this right to law-abiding citizens. Federal law uses this state finding of dangerousness in forbidding petitioner to have any guns. The judgment of the Court of Appeals is upheld.
In Michigan the BATF has stretched the inability to get a CPL license to be enough to activate the "unless clause"
"If a felon is subject to a state CCW restriction, then he or she generally is subject to the Federal firearms prohibition. See 18 U.S.C. §§ 921(a)(20)"
It will be interesting to see what happens!
