I dance with who brung me. I've got at least four different methods. I have an LC Smith that takes a tool (for me) to release the forend...a wheel, and a piece of dowel tapered down to lever the forend off is the tool.

They all work well...lever, wheel-lock, push-button, snap-off. Some are somewhat (IMO) unnecessarily complicated, for whatever reason. Seems it took a long time to figure out a relatively simple solution.
