Paul Harrell has several videos on shotguns for home defense; this one has a demonstration wherein he fires different shot sizes through several mockups of wallboard and stud partitions. At indoor self-defense distances I think #4, 5, or even #6 would do the job.
I don't trust HP ammo to expand consistently out of short-barreled handguns; I keep my .38spl snubbie loaded with fluted ammo, either Underwood Xtreme Defender or ARX Inceptor. The Lehigh projectile used in the Underwood ammo is designed to not overpenetrate. Plenty of videos on these types of projectiles on youtube.
My wife's nightstand gun is a .32H&R Magnum snubbie loaded with full wadcutters - they'll do a lot of damage, shouldn't overpenetrate, and target re-aquisition is quick due to the minimal recoil even at Buffalo Bore pressures.
