Ive got a point blank vest thats rated for 9mm sub gun and lesser threats but I think I can put plates in it, wouldn't the kevlar stop the spalding if it hit a steel plate and how much weight does that add.
How much weight does the line-x add? I can find out I don't know.
The kevlar should stop the fragments, however the one concern I have is the ones that travel 90 degrees to the plate, does the kevlar wrap over the edge. If so I would think you are golden.
When I despair, I remember that all through history the ways of truth and love have always won. There have been tyrants, and murderers, and for a time they can seem invincible, but in the end they always fall. Think of it--always.
