Any answer to this other than "instantaneously" is wrong. If you're in fear of your life, warning shots and shots that will "give them pause" are a waste of time and ammo.
You don't shoot to wound. You don't shoot to scare. You don't shoot to annoy. God forbid anyone would shoot to give pause. The only reason to discharge a firearm at anyone is because the shooter believed they were if fear of losing their life or great bodily harm. If that's true, dispatch the assailant with impunity and without remorse.
If there is genuine fear of life or great bodily harm, that threat needs to be STOPPED right now. Anything less means you either didn't have to shoot or you believe their life is more important than yours.
I think some of the shotgun proponents in this thread are having great difficulty recognizing their ear from their elbow. I, in particular, have some twenty years experience killing things with shotguns with both buckshot and birdshot. Please consider the following for your education since you clearly lack familiarity with the practical capabilities of a shotgun.
•The shotgun DOES require proper indexing upon the target at all times to be effective. The pattern is not sufficiently expanded to be the great catch all for poor marksmen.
•Birdshot for use against targets which can potentially shoot back is ignorant and foolhardy. Be an idiot on your own time and do not advise others to follow blissfully.
•Buckshot is effective at ranges beyond 25 yards even in a cylinder bore choke commonly found on combat variants. The right choke tube can extend the effective range of a shotgun out to over 100 yards with buckshot.
•The further you intend to shoot with a shotgun the larger shot size you will require. This is true for choked and cylinder guns alike; a simple function of inertia versus air resistance.
•00 Buck(0.33" dia.) is likely the most effective size of buckshot for self defense and killing animals up to an including small bears. If you are petrified of over penetration use #4 Buck(0.27" dia.). You will get nine pellets in the standard 00B and twenty seven pellets in 4B.
•Shot fired through a rifled choke tube expands ridiculously fast and cannot be counted on for a reliable and uniform pattern.
• You will get 9, 12, 15, and 18 pellets in 2.75", 2.75" mag, 3" mag, and 3.5" mag in 00B.
•You will not notice any difference in shell length nor gauge when fired in haste or anger.
Okay my rant is over. Please feel free to blaze away clearing the world of scum with great blasts of birdshot. Ha!
It's a twelve gauge. When I point it at them and subsequently pull the trigger whomever is on the receiving end is going to talk to Jesus next. The only pause I'll give is that necessary to chamber a new shell, reset the trigger, and assess if another load is justified.Raises the question: How fast/much do you want to stop an intruder? While birdshot probably won't kill an intruder, it'll give 'em pauseThe other aspect is how far you expect your potential target to be...
Great...the birdshot enthusiasts are back. Why do you suppose the armed forces don't use bird shot? It's a shame that in those fifteen years you had on me you didn't figure out bird shot wasnt for home defense. I have plenty of experience with handguns, but I can also read and the OP said he didn't want to go that route. However, when the mighty shotgun was painted as the room broom by someone who refuses to admit the truth about patterns inside 10 yards, I figured I'd speak up. I will admit this: I have no idea how many rounds a guy with a face full of birdshot can crank off before going into shock. The answer for the buckshot recipient: zero.Never said you didn't have to aim a shotgun. You obviously have to be able to hit your target. However, hitting something with a shotgun does not require the pin-point accuracy of a handgun. Simply put, a shotguns multiple projectiles increases the odds of getting hits. I have yet to see anyone busting clays at the skeet range or bagging doves in the field with a handgun. With your 20 some years of experience (only about 15 years short of mine) you should know it is much easier to hit a cantaloupe at 7 yards with a shotgun than it is with a handgun. Or perhaps you have very little experience with handguns.
Secondly, I would like to see how much fight was left in you after getting a face full of bird-shot from the muzzle of a 12 gauge at 10 or 12 feet, the typical distance across a bedroom. Even if you were high on meth and couldn't feel a thing chances are you wouldn't have any vision left to be able to continue the fight.
Why do you suppose the Armed Forces and many S.W.A.T. teams around the world still use shotguns in house clearing operations?
I have many pistols available. I carry a Sig 229 40 S&W. I keep an old 1980 Remington Wingmaster 870 Police 12 ga. shotgun close in the house. 18 inch, extended magazine with 000 buckshot. Inside a room it will get the job done. Look for an older Wingmaster 870 police shotgun and you will not be disappointed.
I appreciate all of the advice but when it comes to a shotgun, if I was going to use one, I would definitely use 00 buck. No offense to those of you who prefer bird shot... I say go with that if that's what you prefer. As for me, I want to make sure the threat is neutralized and I KNOW 00 buck (or pretty much any size buck) should do the job. It comes down to noise... I do not want to blow my ear drums out. In the unfortunate event that I'm forced to use a gun to defend my life or my family at home I would much rather have to fire a .38 or .45 in my home... or even a 9mm or .40 as I do not think it would be anywhere near as loud as a shotgun. Also, I doubt that too many assailants, even those all hopped up on drugs, would continue to advance after receiving a couple well placed hits from a 180 grain .40 or a 230 grain .45 round (especially if that round is a well known, reliable HP). I know, I know... it has happened... I'm not looking for a litany of cases where a guy has to be shot 8 times by a .45, etc., etc. because I know those stories exist..... all I'm saying is I'm sure that for most home defense situations, a handgun in .357, .38, 9mm, .40 or .45 will get the job done. To be honest, from the limited research I've done, it seems like in about 70% or more of the cases, the home intruder flees as soon as they find out (through sight, sound, etc.) that the home owner(s) is/are armed.I've read most of the replies and some of what I say may be repetitive. Just a few thoughts and a few opinions.
First, bird shot is for the birds and birds only. Many tests have proven that bird shot is an extremely poor choice.
But since you're reluctant to use a shotgun then you must use what you have. IMO you are over thinking things. Don't. The guns you have are more than adequate to protect your home.
Also, you mentioned something in 40SW. There is the possibility that your wife may need to use that gun. Maybe it was close at hand. Closer than her gun. Maybe she picked it up after you dropped it because you were shot or were attacked. She may not like to shoot it or be able to shoot it. Especially if it's a compact 40.
Hand held lights and gun mounted lights must be practiced with. Have a home defense plan and discuss it with your wife. Make sure things are clear as to what your roles are.
Finally, IMO a full size gun is best for home defense. You already have a good one in the M&P. Save your money and buy more ammo.
For the record, my home defense guns are as follows but I do have other guns.
A youth model 870 20 ga with slugs. An M&P 9 full size with Crimson Trace lasergrips. And a S&W 19 with 38 +P. And three handheld lights strategically placed. Both my wife and I can shoot each gun effectively. We have a plan.![]()
To the OP: Sound 357-164.3 Db,9mm 159.8 Db, 12 ga 161.50 18" barrel, no you will not go deaf from firing one or the other, I have and I am not deaf, YET.
Birdshot: I am not sure what size your talking about , but 4,5,6 shot form a 12 or 20 ga at 30 ft or less will provide instant stops with a center chest. I am not aware of any research that shows a "heavy leather jacket" will stop "birdshot", I would love to see the "research". My experience is in the ER and autopsy table, 4-6" ragged hole without heart and lungs proved fatal, immediately. That said I use a semi 12 with 00 buck, I have no penetration anxiety, ( I could 7.62 steel core and not hit anyone). I do not believe there is any benefit in the universal pump sound when someone is at my bedroom door, since at that point they broken into the house, have killed both of my Rotts and are not there for breakfast. 9/40/45 with effective bullets, with good shot placement will all work assuming you have enough light to see, night sights a must. My edc is a sigma 40 f, I own SD40, MP40,glock 22,23,27, plus a few 357 sigs to round that out.there is a 15 rd mag and one in the chamber, a spare next to the light and gun, 2 more mags in the open drawer. Hanging on the wall is a ranger belt ready to go with another loaded sigma and 2 mags,knife, cuffs, etc. Next to the belt is an AR in 300 blk with a can, these are mine, my wife has her own weapons on her side. Last timed response from local sheriffs office was 45 min to shots fired call and they were 8 miles closer, big county , few deputies, not their fault.
Unless you use a suppressor all will be loud. If you want another gun by another spare of your edc or spend the money on ammo, training, and lights.
As stated above this is serious, life changing, treat you tools well, make sure they work, train hard, you are fighting for your life. Do not forget MURPHY!! Be Safe,
