Wow what a great find! Looks sharp.
That seems to be a contradictory statement. If this OMM has a domed screw, how does that show that target stocks were only used with flat head screws?The rear side plate screw is domed and the left grip panel is indented where the screw head is. I believe the grips are original so this would tend to show that target stocks were only used with flat head screws.
Ok,So there was no whittling on the inside to allow for the screw head? The grip was just tightened down so that the screw head crushed into the wood some?The grip has the impression of the screw head in it, slot and all.
