If this is a home invasion and they are clear and intent on doing harm, well, lets just say they picked the wrong house to invade…
do I use;
My Mosin-Nagant M-44 7.62X54R carbine? well, no, it’s far too powerful for indoor use, the bullet could easily penetrate 12+ wall boards and still have energy left over, the muzzle blast would deafen both of us, and if the perp wasn’t felled by the bullet, the muzzleblast would set him on fire and the shockwave would stun him, a home invader is bad enough, but a burning home invader running around, setting my possesions ablaze, now that’s unacceptable… I worked hard for those possesions, and no burning home invader is going to set them afire if I have anything to do with it…
No, the Mosin is too powerful
the .22’s aren’t even worth considering, I want to stop the home invader, not annoy him…
.22’s are out
so it comes down to the Final Four;
CZ-75B 9mm semiautomatic pistol; 15 rounds of 9mm on tap gives it great reserve capacity, but I’d rather not “spray and pray”, I don’t want to have to re-spackle my walls, especially as the 9mm is a fast, light round and could potentially overpenetrate if FMJ rounds are used (I use JHP for home defense), I am exceptionally accurate with the CZ-75 though, and can shoot ragged one-holers all day at 21 feet or under, however, the 9mm is a physically smallish round and may not pack enough “stopping power” for a one-shot stop
Kimber Custom II .45 ACP pistol; If I had to use a pistol, this would be the one, the .45 is a proven stopper, whether FMJ or JHP, the projectile is large and relatively slow**, and carries a lot of energy into the subject, especially when used with JHP rounds, due to the combination of slower speed (less risk of overpenetration) and larger projectile (more tissue displacement/disruption), and the expansion of the hollow point round*** dumps more energy into the target, the .45 is also subsonic and would not have the ear-splitting “crack” of the lighter, faster, supersonic 9mm round, just a nice, meaty BOOM
the .45 would be my choice if I had to use a handgun
12-gauge; THIS is the premier home-defense firearm, it can be loaded as lightly or heavily as you want, shot pellet loads penetrate wallboard far less than rifle/handgun/slug bullets, using a load of 12-gauge 000 Buckshot is like shooting the target with 8 9mm rounds simultaneously, #4 Buck is probably the best compromise between number of pellets/power/overpenetration, however, the fallacy of “you don’t need to aim a shotgun” is false, at typical indoor distances, the shot cloud will not have time to spread, and you will be essentially shooting a large frangible bullet at the perp, so you will still have to aim, the main advantage of a shotgun in this situation is sheer stopping power and lower overpenetration, assuming a center-mass shot
My first choice would be one of my 12-gauge shotguns, either my Mossberg 500 pump, or my Parker VH side-by-side
of course, it goes without saying that after the perp has been stopped, I’d call the police, and report a stopped home invasion, Maine has Castle Doctrine law, I have no duty to retreat, I can stand my ground
**a 9mm would be like getting hit by a Ferrari, a .45 would be like being hit by a full-size truck like a Dodge Ram
*** a 9mm is a .38 caliber bullet (.38 of an inch), reliable self-defense hollowpoints can expand up to a final width of .65ish, a .45 is .45 of an inch, the projectile itself is almost a half inch wide even before firing, a reliable JHP .45 can expand to almost .80, almost a full inch, a 12-gauge slug (think a BIG bullet) is .70 of an inch even before firing, and yes, they do make hollow-point slugs, hollow points generally almost double in size when they hit soft targets…
