Really big Luger question!!

[Thor]

A good 45 Auto or a 4" 357 Magnum is the best defense in a pistol. A shotgun is a good weapon but may be a little unweildy at close range and could make using the phone to call the police a problem, assuming you havent already fired it!!!ANY pistol STANDARD jacketed pistol round will SAIL through the walls of a house, so I prefer something on the order of a glaser safety slug in a good 357 wheel gun, they have LESS problems with reliablity and if you are traveling just switch to 125 gr HPs as you might actually need the penetration on the road. A Luger FMJ will go through 8" of wood and not put that much energy into the torso so if you are restricted to a 9mm make darn sure it can function with a good HP like a Silvertip or Golden Saber round.
