I would have a conversation with the builder. There is a chance that you can’t make a switch to another safety at this point in the game.
I have talked to the builder and would rather not go into the result of that conversation at this time as the discussion is ongoing.
I am of the mind the the angle of the safety lever should be changed so as to be more inline with the cocking pc. The would be either bend the lever or cut & re-weld it and make the change through that.
