Which 9mm/.357 Mag. ammo for home defense?

[Onkel Walther]

Home defense means, that the bullet shall not penetrate the intruder.
Actually, for SD ammo I would go with heavier bullets like 9mm 147 grs. Gold Dot, but which ammo to use for home defense?

Any experience with the Federal EFMJ? What about the real light Magtech First Defense Bullets in 9mm / .357 Mag?
Is there a big difference between Gold Dot 115 grs. and 124 grs. in penetration?

Not really...any bullet that penetrates to the FBI standards in flesh will penetrate many many walls. There's just no way around it unfortuately.

That's why a shotgun is probably your best choice for home defense.
