I was an E5 GMG when I got out of the Navy and was LPO for 2 different ship's armorys. We used these rds for testing feed and extraction when our 1911 and 1911A1s were given scheduled maintenance or to test mags for reliable feeding. The two holes are the right size to pass a small ball chain (like the one on your Dog Tags) through. Alot of guys liked to hang these on a short chain from the zipper of their work jacket.
