What you purchased was supposed to be sold to Law Enforcement only, but there are no legal penalties for selling them that I am aware of. You could face some legal or Civil liability if you ever "used" your new ammo in defense of your life however.
The Winchester Ranger Law Enforcement Ammunition 9mm SXT is the very same BULLET used in the old "Black Talons", just without the black coating on it. Therefore, officially, it is not EXACTLY a black talon.
The actual function of the bullet coating was to decrease friction going down the barrel, which it did to some extent, not to penetrate body armour as many suggested. You are, IMHO, no less protected without the coating on it.
Hope this helps...
