SDR: Nope, actually not. I don’t recommend guns for home defense at all. That might sound strange, coming from an avowed gun person, but, statistically speaking, your own gun is more likely to be used against you during a burglary. If you have kids, you’re really playing with fire in terms of keeping a loaded weapon in the house.
I own a good number of guns and I keep them all locked up in my safe. I store my ammo separately, and neither of my kids know where it is. For protection against burglars, I have a nice 10″ SOG survival knife (which I keep out of sight, but close by the bed) and I’m willing to bet Mr. Burglar will be dead before he knows I’m there. Nice thing about knives is that they never run out of ammo, never misfire or jam and, in the right hands, are absolutely lethal close in.
If you do decide to keep a gun for home defense, discuss 12ga shotguns with your instructor and see if he offers training with them. You can pick up an excellent Mossberg or Remington 12ga from your local gun store (don’t buy at Big 5, please) and relatively inexpensively. Extremely intimidating weapon and devastating at close range.
