I adjust myself to the gun also- up to a point. Depending on how high you hold the gun on your shoulder, will depend on the bead placement. (Tom Knapp did a piece on this not too long ago.) When I shoot trap, like a lot of shooters, I put the toe of the stock in the pocket in my shoulder. I can do that with a pre war Model 21 or I can hold one normally if I want to shoot trap with a SXS. It depends if a shooter wants to "stack" the beads or align them up- one behind the other. If the stock has way too much drop then you can build up the stock with a foam pad if you don't want to change a vintage gunstock. But, maybe you just aren't finding a gun that has little drop. There should be plenty of them out there. There were a lot of six feet men who had large frames before the war that had guns that fit them.
