Magazine safeties are quite rare, particularly those that are still intact. Most of them, if they weren't removed altogether, were clipped to remove the part in back of the trigger that blocked the movement of the trigger when the magazine was removed. I do not have an image of a mag safety removed from the gun, but here is a photo of a complete one...doubt that you can fabricate one from this image but it will give you an idea of what it looks like and how it functioned. I have only seen two complete magazine safeties ever offered for sale. Good luck.
