Probably nothing initially for a few times, but if you repeatedly do this, you may eventually wear out the spring that activates the firing pin or have the firing pin release too far out. There are devices called "snap caps" that fit into the chamber of the barrel and allow you to pull the trigger and release the firing pin into a small spring loaded portion of the snap cap. This is the best way to store your shotgun, with a snap cap in place and the trigger pulled releasing the firing pin into it.
