Wildbill - "it would take a very lucky shot to hit a target that small"...
Wildbill...I think you fine folks might just be using the wrong tool for the job here...
Folks - when at home, you need a shot gun...if you are worried about shattershot, get a slug barrell, the BG on the wrong end will not know and will not ask, i garuntee you... & NOTHING, N>O>T>H>I>N>G, SCARES THE HELL OUT OF A NO GOOD SOB more than a shotgun, as we have said here before, these kinds of people are cowards and selfish, and will do almost anything to stay out of harms way,...and Nothing says "I am in charge and don't move unless i say so" more than a shot gun, it has a gratifing heft, most of them make an awsome awe inspiring confidence building sound when articulated correctly, and (god forbid) when empty can be used as an highly effectly and ergonomic club...12 ga. too big, too much recoil? NO Problem...try a 20 ga. , or a .410,..It doesn;t matter, the BG WILL see the big opening at the end of the barrell and THEY KNOW that nothing but bad things come out of that end....and they make semi-auto in almost every ga. ( LOVE ME SOME SEMI AUTO SHOTGUN and mine is even a 3.5 magnum, and my 00 buck has 19 pellets in the winchester black supreme shells

)
and practice shooting it from the hip while maintaining eye contact with your target... and then use your voice! the LEO's here can talk extensivly about the power of your voice, and how it can be used in confrontations...A determined voice says clearly "i will not be an easy victim, and might just squeeze the miserable little life out of you in the process..."
it is these types of events that scare me the most as a father, husband, brother, son, and friend...and i arm those around me with as much knowledge, firepower, experience, and support as i can...as i believe we are far more liklely to have this kind of an event happen to us or someone we know than some of the other senarios we have discussed here....
perhaps this plays into OC'ing my grim visage for my daughters "boyfriends" and seemily contstanly cleaning my hardware when ever they are over...and my wife laughs at me when i do it...
Carry On, & Do good things!
