I have a Beretta AL391 Teknys and want to drop the heel (I think) as I am seeing too much rib.
There is a plastic shim at the end of the stock that says Dx60 at the top and also a metal shim inside the stock that I have matched up with Dx60 at the top. I think I need to buy a DX65 plastic shim but will I also need to buy a new metal shim that has DX65 on it so it matches the other shim. This is my first gun so I don' really know if I am even doing the right thing to achieve what I want. Any advice would really be appreciated
