I have never personally fired the pistol, but i have seen them at gun shops in Vermont. i just read an article that says the ATF classified the SS196 ammunition as not armor piercing. Even the supposed SS192 ammo did not even penetrate a level II vest. I also read an article about this so called quote on quote "cop killer" that the Brady Bunch did a test and "all of the rounds penetrated the vest. Does this sound alittle contradictory to what the ATF test found? not to mention alittle one sided. Sounds to me that the were shooting at a vest with no trauma plates. IMHO it looks like a glorified 22 rimfire.
