If no round comes out, don't assume the chamber was empty. Extractors do break.
Always lookie-feelie-lookie-feely afterward.
I bought an old expired vest just to have a safe direction to point at. In an apartment complex, there's no real "Safe Direction."
In my old shop, I kept a 5 gallon bucket of sand for this purpose.
My Mossberg 500, Irving, has a shell stop on the left side in the loading port which I can push to the left to pop a shell out of the mag tube. Successive pushes are required to completely clear the magazine.
If the mag is fully loaded, it may be necessary to relieve the pressure of the shell stop by pushing slightly on the bottom of the shell with thumb of the other hand. A little practice makes it easy to do.
