It is not the fact that Reagan signed the law that the ATF is using...it is the fact that they are using that law incorrectly. M885 is not AP. It has not been used in a pistol to injure or kill a police officer...so the argument is baseless.
They did an exemption for it. Surely they intended that exemption to be taken away or they wouldn't have put the bill on Reagan's desk and he wouldn't have signed it. Goes hand in hand with his ban on machine guns as POTUS, signing carry bans & waiting periods in to law in CA, and just an all around lifetime of support for firearms safety laws.
