Quoted:
It probably would go through, but why would it be "more of a threat" than 5.7? How many guns have been manufactured and sold that are chambered for 9x25? How many gun stores can you walk into and buy 9x25 ammo?
They typical thug that shoots a cop obtains his weapon illegally. He doesn't go out and buy one specifically because he knows there's a 9x25 conversion available, and the chances of him stealing one that's been converted are, I'm willing to bet, statistically so small as to be non existent. If I was a street cop I'd be far more worried about facing a stolen milsurp pistol in 7.62x25 than either 5.7 or 9x25.
All three calibers are highly unlikely to be faced on the street. this wasnt that type of conversation, we all know that thugs on the street be packin their NINE'S, forties, thurty eights, foty fives, and whatever they can steal.. This was to say that The bullet is all around more powerfull than the 5.7x28 in every manner yet I have never herd anyone mention it as a handgun round penatrating body armor for that matter. It is more of a threat than a five seven because of its sheer size and weight. the only 5.7 bullets designed to go through level II body armor weigh 32 grns and they are only sold to leo and millitary now etc etc etc there is a company called elite ammo that suposedly sells ammo that will perform like ss190 but who knows... Anyone that owns a glock 10mm can buy a dillion barrel and ammo! nuff said..
