Using it for home protection isn't really a good idea since I can throw a ping pong ball and hit my neighbors' homes, but I bought it and put it together. And its mine....
The CJ needs a new tub, but I got a little sidetracked
I have to disagree.
Not the 'Ideal' home defense firearm (not 'Gun'), but it's a pretty good unit.
First off, MANY police departments are switching to AR-15/M-16 as entry tools.
The .40 cal and 9mm that most departments use in pistol and rifle form will OVERPENETRATE.
That means you can blow away someone in another room pretty easily you didn't know was there.
An AR with 'Mushrooming' rounds (Plastic Noses for those of you in states that don't allow 'Hollow Points') will come apart when they hit something like dry wall, sheet rock, or even better, that old portland cement plaster they used to use years ago.
Hard ball .40 cal and 9MM rounds will blow through dry wall like it's not there, and since they are low velocity rounds built on sturdy frames, they don't deform, deflect, or splatter on impact.
Buy some 'Varmint' rounds, usually light bullet weights, high velocity, and they will come ungluded at the first resistance.
I've had them fragment when they hit weeds on the way to a ground hog, so drywall is virtually bulletproof unless you hit the same spot several times.
If you get some of the military surplus, they are FMJ or Full Metal Jacket, and they will blow through a wall like it's not there.
There are also a LOT of 'Penetrators' out there (They don't call them 'Armor Percing' anymore) that have a solid, hardened core under the copper, and they will shoot through a school with no issues,
So don't use 'FMJ' or 'Penetrators' for home defense...
The light weight 'Varmint' rounds are designed to blow apart when they encounter any resistance, better chance of killing something VERY SMALL, like prarrie dogs,
They expend their energy VERY QUICKLY, and they are ONE SHOT STOP for anyone you are forced to put down...
DO NOT use those stupid "Home Defense" rounds with the buckshot inside, rat shot inside, silicone tips, ect.
With age, the suspension fluid hardens, then they overpenetrate or fragment while still in the barrel and come out as 'Muzzle Blast' or worse yet, baloon the barrel.
DO NOT fall into the 'Gimmic' trap!
You have more crap on your rifle than I carried in combat!
Learn to use IRON SIGHTS! There is no substute for iron sights and PRACTICE, PRACTICE, PRACTICE!
You don't need lasers, pistol grips, night vision, espresso maker, swiss army knife, rear view mirror, curling iron, tampon dispenser, ect.
The best way I can explain it is,
You don't use that crap, and it's more stuff to get snagged and slow you down.
What the Marines drilled into us was if the primary gets snagged, you IMMEDATELY default to your side arm without even looking to see what snagged. Don't loose ANY time doing that and you are in the fight without taking your eyes off the target.
Without a doubt the best home defense firearm is a 20 Ga. or 12 Ga. shot gun with a slug barrel and 'Youth' stock on it.
There is nothing like the sound of a pump gun slide,
Every bad guy in the world knows that sound, and they will jump out a 3rd story window to get away from it!
When loaded with about #4 buck shot, it doesn't overpenetrate, doesn't need to be aimed (just 'Pointed') is fast into action, doesn't get snagged on anything, is short enough to work with in tight places and will knock down a bear at point blank range.
Everyone makes 'Specality' ammo for it, slugs, 00 buck shot, darts, Sabot rounds that will defeat light body armor, and it's by far the most simple and useful firearm you will ever own.
It's also still legal in all states and even most cities (some of the ammo is banned or restricted) but basic bird shot is DEVISTATING at close ranges, so it's VERY good for home defense.
Since I practice a lot (compaired to most firearms owners) I have a 1911 Colt Semi-Auto pistol that Does NOT jam.
(Revolvers are usually recommended for personal defense because they are reliable as an anvil and shoot anykind of rounds you can come up with)
If I were leaving the 'Little Woman' home alone, I ALWAYS load the 12 Ga. and leave it where it's handy for her (No kids in the house, and she shoots clays, so she knows how to handle a 12 Ga.).
Hope this helps relieve your guilt for buying that rifle,
You will find it's a TON of fun, easy to practice with (Made for guys that couldn't get out of the draft and couldn't keep a job flipping burgers),
And if you buy a .22LR conversion kit for it (Replaces bolt carrier and magazine) you can shoot .22 LR ammo for practice, even for women and kids that you normally wouldn't have fire it with full size .223 Rem ammo...
Dual purpose is ALWAYS good! Takes about 30 seconds to switch over to .22 LR ammo, and depending on barrel twist rate, they are fairly accurate, plenty accurate enough to plink cans and bottles with!
