I have a cousin who was a high roller back in the '70's and early '80's and also an avid shooter and hunter.

Immediately after seeing the one Dirty Harry flick with the Automag in it, he ordered one directly from the manufacturer. When it arrived, he noticed the serial number was 3 (I believe) zeroes and the number 1.

He contacted them and told him what they had sent him, thinking they might want to hold on to that one. Their response was along the lines of, "What, is there something wrong with it?" When my cousin told them it was perfectly fine, their response to him was, "Then enjoy."

The gun is long gone (stolen) but he still has 4 boxes of .44 Automag ammo.
