Just for the record, let me address a few common misconceptions that haven't been specifically discussed...
Black Talons are NOT intended to be armor piercing, and they do NOT pierce body armor significantly better than any other commonplace hollow-point self-defense round.
As jmwyles correctly states, the black coating is Lubalox; it is NOT Teflon.
Legal regulations re: the sale of armor-piercing pistol ammunition WERE passed in the aftermath of the Black Talon controversy, but the legislative language was watered down from what the gun control factions wanted, and the regulations do NOT address Black Talon-type ammo.
The Black Talon controversy is better characterized as a historic example of a marketing campaign gone wrong- the gun equivalent of the Infiniti "Rocks & Trees" or the Cadillac Catera dancing cartoon duck.
