- LyndsySimon 9y agoI don't understand - what about it is "chilling"? The 5.7x28mm would be a terrible choice for someone wanting to kill a large number of people. It's reason for existence is a tradeoff between the number of rounds one can effectively carry, armor penetration, and terminal performance. In short, it's designed for use in compact full-auto firearms - PDWs ("Person Defense Weapons"). That class of firearm has not been readily available in the US since 1934, and the P90 has never been available.
- asmithmd1 9y agoThis gave me pause: "The 5.7×28mm SS190 has a muzzle velocity of roughly 716 m/s (2,350 ft/s, Mach 2) and can penetrate the NATO CRISAT vest or a Level IIIA Kevlar vest at a range of 200m"
- novembermike 9y agoI'm not sure what's scary there. It's got a low velocity for a lightweight round and penetrates light armor. As a trade off it doesn't have great terminal performance against people.
