What would you do?

How would you destroy the staircase with only a gun and a knife? :/

You can keep hacking at it with the knife. Plus survival knifes have a serrated side that can act as a saw.

I would like to point out, that yes. Destroying the staircase would work, however, it would be in-accessible to the user. What I wouls suggest (which would be completely insane but funny) is a house of ladders *grins* Then you can get around and the zombies be doing snakes and ladders getting to you ^_^
