5.7 was made in an attempt to have a pdw for gov/military applications. And to penetrate lvl 2 body armor. Yes it works too. Better in the p90 than the five seven. And the penetrating ammo is restricted to gov/le use only. Personally i think its a great round but the civilian legal round isnt worth while.

Bingo... With military ap ammo it's an effective PDW and sidearm round for rear echelon forces, which was its intended purpose.

Pushing civi legal rounds, I would waste my time on it.
