Extended mag release remake

For the past couple months I've been working on a project, since they don't make them anymore and I have a good bit of 3d models/multiple designs for extend mag releases, I made a handful prototypes of a couple of designs out of polymer before hopefully going to metal and would like some input, what would you guys like to see, longer, shorter, wider, more swept back, a leg to hit with trigger finger? Aluminum or steel? The polymer ones are already holding up very well and lock in just as good as the normal one. I can make anything yall would like to see, I could make a paddle that's 10 inches long if someone wanted.
