So I was reading a book and it said he shot it with a .22 Caliber and yet it did not say what so I assumed it could be a pistol to an assault rifle. Caliber is diameter and I hate when people misuse it.
Actually, yes and no. By convention, a .22 cal will almost exclusively refer to a .22 rimfire round ? generally the .22 LR as used in plinking rifles and competition pistols, but also things like the .22 short and the .22 WMR.
Assault rifles generally use the .223 (or, near as makes no difference, 5.56mm) cartridge, which is a full-size centre-fire cartridge. But they are never referred to as .22 ? because they aren't.
.003" makes a big difference in ballistics.

And the almost reckless abandon with which people use sniper rifles in video games and many movies. For example, Smokin Aces (a movie which I love) in the scene when Georgias partner goes bezerk with a 50 cal. because you know, kick back doesnt affect the trajectory of the next shot at all

Basically, what im saying is you couldnt place that many shots in that small an area with that rapid of succession without having the gun nailed down or something (which im pretty sure didnt happen in the movie, correct me if im wrong though.) you would have to take the time to re-align each shot, which didnt happen.
Now, I don't remember the scene you're referring to, but some .50 cal rifles certainly are capable of rapid and accurate follow-up shots. See this USMC demonstration of the SASR (Barrett M82), around the 6:39 mark:
So the capability's there ? whether the circumstances in the film work in its favour is another matter. ;-)

OT: Pretty much the laundry list of things people who play Call of Duty but never use real weapons think. Namely that you can fire full auto with any semblance of accuracy with anything.
But you can. With practice one learns to control the recoil, particularly with modern in-line weapons, so short bursts can be if not target accurate, then certainly combat accurate at short ranges. What really annoys me in games is the huge reticle bloom they tend to have ? if I'm walking along while shooting, the bullet's still going to go where I'm aiming, not kick up dust around my feet. It's an attempt at realism that actually makes it less realistic ? much like the jam/wear mechanic in Far Cry 2 or one-shot kills in, well, everything.

Yeah, cocking back the hammer is not needed for modern pistols because when you pull back on it to chamber the round it automatically cocks the hammer, and usually the pistol is all ready to shoot as soon as you pull it out and pop the safety off.
"Modern pistols" in this instance meaning "anything after about 1890".
Cocking the hammer manually is needed on any revolver or pistol (regardless of vintage) that fires in single-action mode only. With automatics, racking the slide to chamber a round will cock the hammer as part of that mechanism, but it can be decocked for safer carry ? then it needs to be manually cocked to fire. That's why many people who carry 1911s tend to carry them "cocked and locked"; in other words, hammer cocked and safety on.
DA/SA pistols ? like the Sig P220 series, for instance, or Beretta's 92 range, or the vast majority of pistols from the 60s through to about the early 90s ? are loaded and chambered just the same, but can then be decocked so the hammer is dropped safely without impacting the firing pin. They're then drawn and fired in a double-action mode ? where pulling the trigger first cocks the hammer ? and subsequent shots are fired in single-action. The main downside with this is that the first shot has a heavier trigger pull and can tend to go wide.
It's worth noting, by the way, that 20th-century firearms have tended not to really go out of fashion ? new developments come along, but older mechanisms still stick around. The 1911, for instance, is still as popular as ever, the US Army still retain the M9, and so on.
DAO (Double Action Only) pistols
don't leave the hammer cocked after firing, and always fire with the heavier trigger pull.
Striker-fired pistols don't have an external hammer ? the Glock pistol is probably the most notable example. More on them later.

...I dont feel safer with a gun around since I mean if you really need it there are so many steps to take before you can use it, you need to un-holster it then you need to chamber a round and flick the safety off and aim then fire, wit ha knife all you need to do is grab it and flick out the blade and if your 20 feet apart then chances are that knife will get to you before the gun is ready to use
If you're carrying a gun for self-defence you will almost certainly carry it with a round chambered. You would also practice your draw to make sure that all the requisite steps can be accomplished as part of it ? on a 1911, for instance, your support-side thumb could sweep down the side to release the safety as you complete your firing grip. (Even chambering a round needn't add more than half a second.) With many DAO or striker-fired pistols, there are no external safeties to worry about ? get a proper shooting grip and it's ready to go.
You're right, though, about the knife ? in general, if someone has a knife within seven metres of you, you won't have time to draw and fire a gun.
derdeutschmachine said:
also on point for the original post here. there are hundreds of guns chambered in the .22 cal range and currently most military forces use the .223 which is a variant of the .22.
Actually, the .223
isn't a variant of the .22 ? there's only a 0.06mm difference in the bore, but the cartridges are two very different beasts. The .223 is a full rifle round, with a necked cartridge and lots more powder. The bullets are roughly the same diameter, but that's where the similarities end.

The only steps I have to take to use my Glock when I carry it is pull it out and shoot... Yes, that's right, I carry it chambered.
unless you also carry it without the safety off someone can close that distance really fast and you would be lucky to get one good shot off with it before the knife was at you and if you carry it chambered with no safety then thats just stupid
The Glock 17 has no safety. It will only fire with a proper trigger squeeze. They are damn safe.
I still wouldnt trust it, are you sure there is no chance of you or anyone else accidently grabbing it and firing off a round?
Kwaren's right on this (well, mostly ? the Glock
does have safeties, but they're all internal and automatic). The Glock "Safe Action" pistols have trigger safeties, so there's a small nub on the trigger that has to be depressed to allow the trigger to move. Many striker-fired pistols use similar systems these days. For an example, here's a video of me firing a Smith & Wesson M&P (which uses a similar trigger safety). At about eight seconds in, I pull the trigger and nothing happens. Now, I hadn't used striker-fired pistols much at this point, so my first instinct was that the gun hadn't gone into battery properly, so I just unloaded, cycled the action and started again.
In retrospect, of course, I'd simply been sloppy with my trigger finger placement. So that's how safe these guns are ? you can even pull the trigger, and they won't go off unless you pull the trigger
the right way.

One thing that's really starting to grate on me is how I've never seen an accurate depiction of a chaingun. It doesn't go "dakka-dakka-dakka" like those orks are always talking about, it sounds more like an exploding chainsaw. It's like just one loud, continuous, buzzing roar.
That's miniguns ? chainguns are single-barrel designs, which don't go up to quite the same extremes of firing rate.
But yeah, miniguns firing with distinguishable shots annoy me ? that's why I was so pleased when I watched
Black Hawk Down the first time.
Another related thing: miniguns spooling up in computer games. Real miniguns load and fire based on the rotation of the barrel assembly, and while some have clutches to stop rounds loading after
releasing the trigger, they start firing as soon as the barrels start revolving. Always annoys me, particularly in games that should know better.

P.S. and suppressed revolvers...there is only one that I know of that could acctualy use use a suppressor and its horribly outdated.
The only true silent gun was the suppressed revolver and I forget what the rifle was but they had very long suppressors and I think they were built in the gun but I'm not sure about that.
There have been a number of very quiet guns; the MP5SD series, with its integral suppressor, is very quiet, though the sound of the mechanism can still be heard. Ruger make a .22LR pistol with an integrated suppressor, which is barely audible. Almost any bolt-action rifle with a subsonic round and a decent can will be near-silent.
But the daddy of them all has to be the De Lisle carbine, developed during WW2. It fired .45 ACP rounds ? big, heavy, slow rounds ? through an integral suppressor. Almost completely silent, except for the firing pin falling, and on that rifle that's not a loud sound.
Revolvers generally can't be suppressed ? after all, for the cylinder to be able to rotate, there has to be some clearance between the frame and the cylinder, and firing gasses escape through that. I have heard of the suppressed revolver you mention ? some custom job ? but I can't remember anything about it. The key point is that in films, they suppress revolvers all the time, and it simply doesn't work like that in real life.

It may not seem guns are loud in movies and in games but they sure as hell are

I also lol when people think soldiers wear ear protection while out on the field.
Actually, nowadays many do. It is a pretty recent thing, and has really only become possible since the development of active ear protection like the Peltor Com-Tac and Sordin ear defenders. Basically they have microphones built in that amplify sound from outside so the soldier can still hear, while still cutting off any high-intensity impulse sounds (like shots). So yes ? nowadays, soldiers do wear ear protection out in the field!

Most semi-auto pistols you can decock by easing the hammer down while pulling the trigger. It allows you to keep one in the chamber without worrying about it going off.
Some guns are designed to be able to do that, and with others it's developed into a (relatively) safe technique. But in general, one should always assume that if you pull the trigger, the gun's going to go off. "Easing the hammer down" is not something one should habitually do ? particularly as many guns that aren't intended to be decocked don't have provisions for it on the firing pin and hammer. This means that a jolt could theoretically jostle the hammer enough for it to bounce onto the firing pin and fire the round.
Many modern pistols ? Sigs, H&K USP, Berettas - have
decockers, levers that safely drop the hammer, generally by moving the firing pin out of the way.
crimsonshrouds said:
dont much about guns but the idea that a pistol can be fired accurately with only one hand and duel wielding can be accurate in the slightest is facepalm worthy.
Actually, pistols can be fired very accurately with one hand ? just look at competitive pistol shooting, where a bladed (=side-on) stance is used. The key thing is that in combat, you've got adrenaline pumping, distractions, and all sorts of other factors to consider; the additional stability given by a two-handed grip counteracts those things.
And dual wielding can be done... not in a combat situation, but FN Herstal once released a video of one of their testers firing a P90 in each hand with relative accuracy. Granted, it was to demonstrate the lower recoil impulse of the SS190 cartridge, but still. :-D

I'm also a big fan of that magical noise guns make every time you raise them, especially when you do so a part of a group.
And the magical *schiiiiiing* noise swords make when drawn. I have many varieties of swords, none go *schiiiiiiing*...
It's an old cliché, though. Some scabbards have actually historically had a small piece of metal built into the opening to scrape along the back of the blade and create that sound. But they were explicitly for psychological effect, and certainly not the norm.
And yeah, the constant clatter of gun mechanisms... I mean, do coppers in films not chamber a round until they're aiming at the bad guy?

I was really annoyed in reading one of the millenium books where they constantly referred to hollowpoints as "hunting ammunition", these were police officers talking, why wouldn't the use the correct terminology?
That's the Salander books, rather than Frank Black, right? I can imagine that sticking out to a non-Swedish shooter, but in context it makes rather more sense. (For given values of "sense".)
Basically, they used to useNorma Säk, a fully-jacketed round. In 2003 they switched to Speer Gold Dot ? a far more effective police round, and also one less prone to overpenetration because, as a hollowpoint, it'll mushroom and most likely stay inside the body of whatever it hits.
There was a bit of a furore about it at the time, with even Jan Guillou (who should know better) writing an article about how this was "hunting ammunition designed for maximum damage" and "so cruel that it's forbidden even in war". Add to that the fact that Sweden doesn't acknowledge that self-defence is a justifiable purpose for a gun, and you end up with a sort of folkloric distinction between jacketed rounds (to use against people in war) and hollowpoints (to put down an elk quickly). So yes, they were using correct terminology
in the context.
