Some experts (Mas Ayoob comes to mind) actually recommend the pistol as the first response to a home-invasion scenario. Easier to manipulate in tight spaces, harder for the bad guy to grab/deflect, and leaves a hand free to dial 911. Your mileage may vary, etc.
I prefer the pistol, for those reasons. More training is required to reliably put lead on target. Pistol loads that won’t penetrate wall etc… are available.
