It should be plenty long. I also wouldn't worry about bringing the armor out and away from the vest, the armor should sit comfortably tight against the vest.I will be using this method .... thanks for sharing it !!!
Question: The posts on the pins I received are 10mm (3/8 inch) long. Is this long enough to go through the vest with the backs attached ..... or should I look for pins with longer posts ?
I was also considering gluing a small round piece of plastic or ply, about 1/8 inch thick, between the pin and the armor, to bring the armor out (away from the vest) a bit. Good idea or bad idea ?
