Hmmm, Don't know about those,The ones I looked at briefly belonged to a prison guard up in Wasilla Ak,They were black with a sharpened point.
His ex-wife was having a Heaintpaidchildsuppotandalimony sale out of the garage...We bought 5 firearms at a decent price too,I walked away from the ammo !
Might have been Black Talons. They were discontinued almost before they hit the market. That was only because the anti-gunners thought they were armor piercing (though they weren't) and campaigned to be rid of them. You would be hard-pressed to find some now, since they have been off the market since the early 90s.
