I’m also a big fan of surplus police kevlar panels. This shop has sold me scores of them for $50 each: http://www.bulletproofme.com/Bullet_proof_Vests_Catalog.shtml
I’ve got one by my nightstand revolver to use as a shield in one hand. Takes no time to pick it up with my pistol.
Likewise, keep in mind that some home invaders have recently been arrested wearing body armor.
thanks for the tip,
