While out doing a little gun hunting last week I ran across a S&W 29 .44 Magnum in a pawn shop located deep in the hood. Someone drilled holes in the frame of this poor thing in a place I have never seen holes drilled. I asked the owner who is a real good guy, but he had no information on the guns history. I asked if I could snap a few shots of it to post on a few forums to find answers as to "Why someone would drill holes in those spots".
So far nobody at THR or the S&W Forum has recognized the hole hole placement and come up with the definitive answer.
