I just purchased my first shotgun and its a Montefeltro 20 ga. I love the gun, very light, elegant, and sleep and fits my small frame very nicely. I have a small problem. When I shoulder the gun, I see too much rib, which means I need to increase the stock drop. The gun did not come with any shim kits (apparently older models did). The shim in the gun now is shim "C", so I was looking for a shim "D" online and could not find one anywhere for this model. Does anyone know if Benelli makes a shim D (and the corresponding locking plate) for the new Montefeltro 20 Gauge?
