I have a newer Mossberg 500A. Probably a dumb question, but why is a short 18.5" shotgun barrel considered best for defense use? Does 8 to 10 fewer inches give you a better advantage? Is it worth buying an additional short barrel for defense purposes?
 
I think the extra 1.5 inches for a 20 inch barrel wouldn't add much length, but it apparently adds 3 shells capacity? My 18.5 inch mossberg only holds five 2 3/4 inch shells, but I read that the 20 inch version holds eight?

Not to get off topic or anything...
 
I suppose the shorter barrel is more maneuverable.

+1

Pie'ing around corners with a 20"+ is really rediculous as there would be no way to NOT put your barrel in an area that you cannot see or control. That makes for a possible situation that wouldnt be so fun (especially if a BG got his little mitts around your barrel/firearm) :(
 
IMHO, 10.5 inches is the best length for self defense - at least indoors. But I am biased. Of course, the $200 tax stamp does add to sticker shock.

If a guy grabs the barrel - you could lean backwards and he'd be pointing the muzzle straight at his chest. And it seems to me that you moving backwards is pretty much an instinctive, reflexive reaction.

I'm not calling shennanigans, but I'd like to further understand what good it would do the guy to grab the barrel. I can see how it'd be better than if he didn't grab the barrel, but still if he grabs it then he's automatically pointing it in his direction.

But I like my 14.5":)

It would'nt be too difficult to snatch a firearm away from my wife if you got your mitts on it. The shorter the firearm the harder it would be for a BG to get it their hands on it and thus harder for them to take it away :D

I am sure that every guy on here can understand that its VERY difficult trying to teach your wife small unit urban tactics/house clearing defense techniques when CSI or Everyone Loves Raymond is on TV.... I give her a Glock, she shoots it at the range, and I know it would work for her if needed. HAHA
 
The shorter barrel is easier to use in close quarters. Try it sometime and you'll see. Also, gun grabs are a concern...the whole "lean back" thing assumes that the guy grabs the muzzle and just stands there. If he pushes it aside and closes you have problems...you might not lose the gun (or, you might), but he will be inside the range at which you can effectively use it, and you're now exposed to whatever he has (gun, knife, hands). This can happen with a shorter weapon, too, but it is harder.

Also, adding a mag tube extension to a SG of any length adversely affects the balance of the weapon. How much depends upon length (the longer, the worse it is), and whether or not it is worth it is personal preference.

"BEST" is a four-letter word 8^).

There are few things in any realm that are 'best.' But lots of time and electrons are spent in the pursuit of 'the best.'

Maybe I'm too easily satisfied, but I find that very often 'good enough' works just fine for me.

Now if your plans for home defence call for you to go jousting throughout your residence with your shotgun couched like a knight-errant's lance (and the strains of the William Tell Overture sounding softly in the background- http://wilstar.com/midi/willtell.htm ), barrel length might well make a difference to you. But if your intent is to barricade yourself behind a substantial piece of furniture in a position where you can cover the only door to your saferoom, and remain there while calling the cavalry via 9-1-1, a fowling piece might be viable armament.

What's 'best' kinda depends on what your circumstances and plans are. As well as on your training and experience. Gunfights are often a pretty poor place for the inexperienced to improvise off the cuff solutions to sudden problems, after all. You might want to work on a few options before the shooting starts.

And hardware is usually the LEAST of those problems...

Stay safe,

If you're paranoid about barrel grabbers you can always mount a bayonet....:eek:....in which case you might consider the 20 " mossberg or a winchester "trench gun".

I dunno.

See Lee's post above.


I have had Ithaca 37, Model 12, Model 97, and 870s, that were "Police" or "Military" guns, with barrels ranging from 18.5" to 20".
I did not do anything, but pattern the gun and become one with the gun.

Bone Stock Model :
Winchester 97, 12, 1300, 1400,Super X Model 1
Ithaca 37
Remington 870, 1100, 3200 (O/U).
Beretta 303,
Browning A5, BPS, Citori
Stevens 311
Perazzi MX8
Kreighoff K20, K80
H&R Topper
Aya SxS

Gauges: 10, 12, 20, 16, 28, .410, 24, 32.
Barrels from 18.5" - 34"

Its a shotgun. It cannot do a darn thing all by itself.
It has to have a user, and no tool is ever any better than user of said tool.

I dunno.

I personally like 21" and 23" barrels for Serious Guns

Take a English Bird Gun, like a 1100 with 23" barrel and run it through any COF, see what you think.

28" barrels for too many years have been what I use most.
Take a SX1 I have over 300,000 thru, that gun has been used for everything, including Serious use.

It will take care of a Serious Situation, I know.
 
With a long barrel it is easier for a BG to hide behind a corner and grab the barrel as you are searching. In this position the BG has leverage over you.

He can grab ANY long gun easier than a snubby revolver. I don't have a shotgun for moving around the house, I have it for the safe room. He breaks through that bedroom door, he's dead. I've already called 911 for the mess clean up.

If I do have to move about the house, I have a snubby.
 
I don't have a shotgun for moving around the house, I have it for the safe room.
Exactly and in that situation barrel length very little difference. While I have a 14" barrel for my 870, my plan is to leave house clearing to the experts. Owning or having owned 14", 18.5" and 20" for PC purposes I prefer the 20" with rifle sights.
 
According to Remington, most of the powder is completely burned up between 10 and 14 inches. So you can thank the Fed'ral Gubmint and the ATF for your less potent home defense weapon.:scrutiny::cuss:
 
i dont search my house if i suspect a break-in...... thats suicide to do so without a partner........


i would take a strategic possition and let the cops sweep the house properly...
 
Anyone have a real experience about a barrel being grabbed? I sure don't.
We did some drills in training with a demilled 870. That's about it.

It strikes me as a low probability of success endeavor on the part of the grabber, but I'd still not want to be the grabee.

Oh, and I did witness a suspect grab the barrel of an M16 and try to move it offline. He was successful. So successful, in fact, that the butt came around and struck him in the jaw. ;) That was the ultimate culmination of a series of stupid moves, only one of them made by the officer (closing too much).

My Win 1300 has a 14'' barrel. Now it feels just right as far as handling it goes.
 
When I built my wife her 20ga Ithaca 37 Ultra light I went with a Deerslayer barrel which came in 24". I could have cut it down, as I did the stock (BTW GunTech your very cool gun needs the stock knocked down a couple inches to REALLY be useful for the purpose it's built for)but decided she is not gonna clear rooms, the blast seems a lot less with that 6" longer barrel, and most of the time she is gonna be blasting vermin.
Most of my defense guns are 18.5" although some are 20" .
 
18.5" because someone "smarter" than us subjects decided that anything shorter than 18" was "too destructive" for the proletariat to own. Or -- as suggested in the article below -- too effective for protection against the crooked politician-mob complex.

As a result of this Federal loophole through the heart of the Constitution, the Federalis are soooooooo stringent on this 18" measurement that the collective gun-owning consciousness has added an extra 1/2 inch for safe measure. BAAAAAAAAAAAA! (And believe me...I am in that sheep chorus. No need to mess with silly, but heavily-enforced arbitrary rulings).

A person should be able to have whatever length barrel suits his/her needs or his/her fancy. You say To-MAY-To...I say a shotgun I can fit into a holster.

It's in the Bill of Rights. You can still even look it up, but you can't enforce the Bill of Rights anymore.

The Ithaca Auto and Burglar
By L. Neil Smith
[email protected]

Exclusive to The Libertarian Enterprise

The faded magazine ad haunts us across six long decades of stupidity and corruption:


"Here's the Ithaca Auto and Burglar gun, the so-called "Sawed Off Shot Gun" which holdup men fear because its load of sixteen buckshot spread over such a wide circle that a poor gun pointer, who would miss with a revolver or pistol ... is very sure to hit ... handy to carry in the pocket of an auto or in a holster ... Detective Harry Loose ... first induced the banks in and around Chicago to use it, then its use spread to sheriffs, police departments, paymasters, watchmen, express messengers, and it's a wonderful home protector. The U.S. Army demonstrated what American shotguns ... would do during the late war. This Ithaca Auto and Burglar Gun weighs about 1 1/4 pounds, it has 20 gauge 12 1/4" barrels, cylinder bore ... Price, including excise tax, $40.55."
The Ithaca Auto and Burglar was a veritable marvel in its time, a near-perfect blue steel and walnut "magic wand" of self-defense, against strong-arm artists and protection racketeers in the age in which it was introduced, ideal -- because of its light weight, moderate caliber, limited range, and short length -- for women, the elderly, and children who might require it, not only against house burglars, muggers, and the like, but against an abusive or incestuous parent.
If John Lennon had been carrying an Ithaca Auto and Burglar under his coat, the Fab Four would be selling live albums of their fifth reunion concert by now.
It is illegal -- or, more accurately and revealingly, placed beyond the reach of all but an economic and political elite -- and has been since 1934, because its 12 1/4" barrels are 5 3/4" shorter than federal law mandates, and its overall length -- roughly 20" -- is shy, by about the same amount, of the minimum length specified by a statute that should never have been passed or judicially upheld in a nation with something like a Second Amendment in its Constitution.
When I was a kid, my first lesson in politics arose from the fact that my home town, Fort Collins, Colorado, was "dry" -- which is to say that it was illegal to sell "adult beverages" within the city limits, and had been since Prohibition. What made it educational was that this imbecilic situation was maintained at the polls every year by a tacit coalition of self-righteously muttering church ladies like my own grandmother, and -- to begin with -- by bootleggers who plied their trade inside the town, and later on, by proprietors of bars and liquor stores that came to surround the "Choice City" in a tight ring.
If you understand that, you understand the politics of victim disarmament -- commonly and improperly known as "gun control". National politics of the 1930s were dominated by an unprecedented violence and corruption that sprang directly from trying to outlaw production, distribution, and consumption of ethanol. Every bit of the criminal activity -- gang-wars, drive-by shootings, summary search and seizure, asset forfeiture -- that we have come to associate in our times with drug prohibition arose, to begin with, in the "Roaring Twenties".
In those days, Al Capone was the most politically powerful individual in Chicago, in the Midwest, and possibly in the United States. He purchased city councilmen, state legislators, congressmen and senators the same way that I (the daddy of an electronic-age seven-year-old) purchase AA batteries. Others of his kind did as much of the same thing as they could. I leave it to you to figure out whose interests were really being represented in Congress in 1934.
The "weapon of choice" for creatures like Al Capone was hardly the Ithaca and Auto Burglar, or even the infamous Thompson Submachinegun, it was the lives of countless revolver-carrying cannon-fodder thugs, and the influence of crooked politicians.
Who was really protected by the Ithaca and Auto Burglar and the Tommy Gun? Shopkeepers, householders, and especially truck drivers whose vehicles were often stopped and stolen (just as Florida pleasure boats are today) to serve as disposable conveyances for illicit alcohol. One store proprietor with a "sawed off" scattergun could discourage three or four goons who'd come to collect. One truck driver with a "Chicago Piano" could run off a dozen highwaymen.
As surely as the Gun Control Act of 1968 was passed to disarm the militant non-nonviolent blacks who were threatening to overturn the political apple cart ...
As surely as the Brady Bill was passed because a certain variety of men -- well-represented in politics -- are mortally afraid to see women begin to arm themselves ...
As surely as Bill Bennett and Bill Clinton's rifle and magazine law was passed because -- in this dangerous age of multiple assailants, when a single individual's only chance against a gang is often firepower, and the ideal weapons of self-defense are semiautomatic rifles and pistols -- both right wing and left wing socialists couldn't bear the humiliation of Korean store owners successfully defending themselves against their clients during the LA riots ...
The Ithaca Auto and Burglar was stamped out because it threatened gangsters and hijackers who were the real constituency of the congressmen who outlawed it.
Now Daniel Patrick Moynihan crawls dripping out of his butt of Malmsey to attack expanding handgun bullets with a proposed 10,000 percent tax, exactly as he earlier attacked small caliber cartridges. Why? Could it be because they're effective for use by ordinary productive class people against the freelance thieves and muggers who, as a statist, Moynihan naturally identifies with?
Write Moynihan. Ask him. And while you're at it, ask the sonofabitch why he shouldn't spend his long-overdue retirement behind bars, for having tried to deprive every man, woman, and responsible child in this country of their unalienable individual, civil, Constitutional, and human right to obtain, own, and carry, openly or concealed, any weapon -- rifle, shotgun, handgun, machinegun, anything -- any time, any place, without asking anyone's permission.
Ask him.

Not to get off topic or anything...

Your 18 1/2" mossberg has a mag tube that ends well short of the barrel....if it went all the way like an 18 1/2" 870 with a +2 extension you would have 6 in the tube plus 1 in the chamber (7)
The Mossberg 20" has the full length mag tube and is equal to a plus three mag extension on the 20" 870.
So 4 plus 3 is 7 plus 1 in the chamber (8)
I don't agree with manufacturer's that list their gun's mag capacity to include one in the chamber.....
