Basic firearms stuff:
This is my rifle, this is my gun . . .
Generally speaking, the military refers to a shoulder fired firearms as rifles and uses the term gun to refer to artillery pieces. Aside from angry drill instructors, the distinction is meaningless. If someone chastises you for using the term gun, ask him what they use in a twenty one gun salute.
Rules of gun safety
Treat all guns as if they are loaded.
Never let the muzzle of a gun point at anything you do not want to destroy.
Be absolutely sure of your target, and what is behind it.
Keep your finger off the trigger until you are ready to shoot.
Bullets
Guns shoot bullets. The thing that goes in the gun is called a cartridge. It has a bullet, gunpowder, a primer, and a case to hold it all together. Some people load their own ammunition by reusing the cartridge case and new powder, primers, and bullets. If you go to the gun store and ask for a box of bullets, you might get one. They sell the bullets by themselves, and using the word bullet when you mean cartridge will send most shooters into fits.
How do guns work?
The primer in a cartridge explodes when struck with enough force. The flame from the primer lights the gunpowder charge. The pressure from the burning gunpowder pushes the bullet through the barrel.
Does gunpowder explode?
Not literally. Fires and explosions are classified by the speed of the burning stuff. If the flame spreads (propagates) slower than the speed of sound, the material deflagrates. It burns. If the flame propagates faster than the speed of sound, about 1,100 feet per second, it detonates.
So why do bullets go faster than the speed of sound?
The speed of the bullet comes from the volume of the burning gunpowder, not the speed at which it burned.
Whats the difference?
If you take a pound of gunpowder and ignite it in an open field, it will burn very quickly, but not at the speed of sound. If you take a pound of TNT and fire it in your open field, it will burn faster than the speed of sound and it will create a pressure wave. The pressure wave has enough energy to kill a man, even if nothing else hit him.
Dont guns explode?
Yes, they do. Ammunition that was improperly loaded can create more pressure than the gun can tolerate. If the bullet cant move out of the way, for instance because the barrel is blocked, the pressure can also exceed the limits of the gun. This is one of the reasons why youre supposed to wear safety glasses when you shoot.
What are civilian firearm types There are two basic classes of firearms: handguns and long guns. Handguns are designed to be held in one hand when fired. Long guns are meant to be held at the shoulder when fired. Long guns are further divided into three types: rifles, shotguns, rifles, and other. Rifles have rifles barrels and fire a single projectile. Shotguns typically have smooth bores and are designed to fire a load of pellets. Shotguns that have a pistol grip instead of a shoulder stock are technically not shotguns according to the federal law, because they were not designed to be fired from the shoulder. Theyre classified as other and you have to be 21 to buy one from a dealer.
Blackpowder guns, or muzzleloaders, are not classified by federal law. These include antique styled guns like flintlocks, but some modern guns are considered muzzleloaders because the shooter has to load the powder and projectile through the muzzle. These are primarily intended for deer hunting in extended seasons available to muzzleloaders. A modern firearm opens at the breech, the back end of the barrel, to allow a cartridge to be loaded.
Machine guns, sawed off shotguns, and other items are known as Class III weapons because of their designation in federal law. Thats a subject for another day.
So I have a modern gun. What does it shoot?
Any firearm made after 1968 has to be marked with the caliber it shoots. If you have an old gun that was not marked with the caliber, take it to a good gun store and find out. Dont take it to Wal Mart. They have no idea.
My gun says 9x19, 9mm parabellum, 9mm Luger, instead of 9mm. Whats up with that?
Cartridge names have nothing to do with what comes out of the barrel and everything to do with what the maker thinks will make you buy one. Several cartridges re known by names that do not indicate what they are. The .38 Special is the most common. Although there are .38 caliber cartridges other than the .38 Special, the overwhelming majority of .38s in this country shoot the .38 Special. There are other .38 cartridges, such as the .38 Smith and Wesson/.38 Colt New Police/ .38-200 (Webley.) None of these bullets are actually .38 inches across. .38 Specials have a .357 inch bullet diameter. This sounds cool when you say that you have a three fifty seven magnum, but it sounds stupid if you have a three fifty seven special. Likewise, I have no desire to own a thirty eight magnum.
Cartridge names may come from the person who designed them, or the company that produced the first one. They may be named fro the most popular maker and sometimes the names were plucked out of thin air. The first guns to fire the .40 Smith and Wesson cartridge were designed by Smith and Wesson and Winchester. Winchester is also famous for the .300 Win Mag rifle cartridge, but guess who didnt design the .308 Winchester round.
A cartridge design can be patented like any other invention. The owner of the patent, or the common name for the cartridge, may allow others to make it. The name .308 Winchester suggests an obvious source for the rifle to fire it. Some cartridge designs are proprietary. Some are not sold in sufficient numbers to justify a major manufacturers effort to market them.
Whats the best gun for me?
It depends on what youre going to do with it and how much you want to spend. Most people want a gun for self defense in the home. They usually buy some kind of a handgun, even though I tell them not to. Handguns are easy to hold and to conceal, but the effect of the ammunition had to be compromised to make them easy to hold and conceal. Rifles have the most power of any gun, but the bullets tend to keep going. A rifle bullet fired in a home can go through the walls and kill the neighbor. This is called over penetration.
The military issues rifles to soldiers, with handguns as a second weapon or an emergency measure for officers who arent expected to fight in combat. They use shotguns for base security but theyre not allowed in combat because of the Hague Accords. For the home, a 12 gauge or 20 shotgun loaded with buckshot is the most effective available. It does lots of damage because it hits the target with several projectiles at the same time. Each individual projectile hasnt got a lot of energy, so they tend to stop when they hit something. But when they all hit the same thing at the same time, they make a mess.
Handguns also tend not to over penetrate the target, which is a serious issue for those of us who live in condos and apartments. They are also easier to retain. A 26 shotgun sticks out, and it is possible to grab it and control where its pointed. Its not advisable, but it happens. Its more difficult to do that with a handgun.
What if the SHTF?
All bets are off. Get a rifle. You need as much power as you can get. The civilian version of the M4 rifle, the current military version of the M-16, is easy to shoot, holds plenty of rounds, and is the most common rifle in this country. If the world was falling apart around you, parts, magazines, and ammunition for the M4 would be the easiest to obtain.
Should I get a cheap one?
NO. If you needed an operation, would you want the best surgeon or the cheapest one? If you need a rifle for self defense, your life depends on it as much as it depends on the ability of the surgeon holding the knife at your comatose body. Save up your money and get a good one. If you must have it right now, and you havent got a lot of money, get a shotgun. A good shotgun can be bought for $300.
Should I get a pistol grip shotgun?
There is no way to aim a pistol grip shotgun unless you attach a laser to it. Even then, they are not easy to control. They exist because shotguns with shoulder stocks didnt fit in police cars, and they wanted the gun where they could get it quickly. Some argue that the pistol grip shotgun can be fired from the hip. So can a shotgun with a shoulder stock, and it can also be fired from the shoulder.
But I spent $900 on my pistol grip shotgun. It must be good.
I spent fifty dollars on a cheap .38, and I cant hit anything with it, either.
How do I get good at shooting?
Shoot. Shoot a lot. The more you do it, the better you get. Its also a perishable skill. If you dont do it, your ability declines. As much as everyone derides the .22 for being a wuss gun, a .22 pistol or rifle is cheap to shoot and the lack of recoil means anyone can shoot it all day long. Theyre accurate. They shoot .22s in the Olympics. Theyre also fun.
Im going to get a shotty/Springer/Deagle.
If you use those terms in a gun store, you will mark yourself as someone who knows a lot about the internet and very little about guns. The best way to learn is with your ears, not your mouth. Take classes and practice. All those self defense classes exist and teach so many techniques because different methods work for different people. Theres only one way to find out what will work for you. Hit the range.
springer usually refers to an airsoft
My other favorite is “ARMED GUNMAN”.. LOL
Okay; that also makes a certain amount of sense.
Is it limited to air-softs or is it applied to any spring-piston style air-gun?
That’s an exceptionally clean C96! Thanks for posting.
We never heard anything about HIS gun collection.
Yes, I've also heard gankstas call a shotgun "Da Gauge" and a pistol a "Gat".
I kinda prefer 40's slang.. like ROSCOE and HEATER or the Old West HOG LEG lol.
Thank you, thank you, thank you!
Reading "clips" in the newspaper makes me nuts.
;-)
Just about. My Ruger Blackhawk 45LC/.45ACP convertible doesn’t use moonclips
And while you’re at it, maybe your revolver really shoots .45 Colt/.45 Auto.
It's not a critical difference, but if you're around people that are sticklers for technical accuracy, it helps to differentiate between them.
The term "handguns" can be used to refer to revolvers and semi-auto pistols in the aggregate, but when referring to them individually, I like to used the proper terms. I even go so far as to specify DA or SA when talking about revolvers.
I'm sure my 1911 style Llama (a good one) in .380 is SA. I have no idea whether my carry revolver (inherited from grandad) is SA or DA. The thumb on the hammer cocks it as it clears leather. It's automajik. What is the point of DA?

I love that video Tijeras.
There’s another reason. Newbies have enough trouble getting an understanding of firearms. There’s no reason to further confuse anyone just because someone wants to sound like an expert.
One of my first purchases was the book “Cartridges of the World”. When I found out there was half a dozen copies at a half price bookstore I bought them all. I sold them at cost to my friends. The only problem I found was there is never a listing for 4MM rimfire Flobert.
A classic.
Same here
Holy s***! Those look like artillery rounds!
I don't do it to "sound like an expert," but to help newbies better understand the things. I'm an NRA instructor with 16 years experience, so I've done quite a bit of that. The DA/SA difference is not a difficult concept, if explained properly.
How 'bout double action automatic revolver?
Yeah, it's mine.
Um... I’m not sure, but wouldn’t a revolver be one that has a revolving mechanism to present the cartridge to the firing pin and barrel? Then everything else would be a pistol? Dueling pistols were just one shot, right?
