Making the release lever swing both ways isn't hard. I did this to my Stoeger. Remove the stock and the release rod and spring. That allows the locking lug to pe pulled back, allowing you to pull the locking lever out of the top of the action. Notice there is a "bump" on the left side of the top of the round part. That bump is what is stopping the release lever from being pushed to the left. I filed that off f mine and reassembled. Now my release lever will swing either right or left.
NOTE:. I am not a gunsmith, just a kitchen table tinkerer. It worked on mine, but do his at your own risk. Hopefully others will chime in, either for or against this mod.
