I dont think the 5.7 JHP would have a problem. That's the thing with soft armour being woven, small pointy projectiles with lots of Velocity have no problem penetrating it. Now a slower larger diameter projectile like a .45, 9mm, etc. are too large of a diameter & too blunt of a nose to get through the woven material.I could bring a FN 5.7 to test those ballistic panels with. Only have JHP though, not the good stuff
