Not sure if this is your domain, but I will still ask a general question: Using guns. What are some common tropes that people get wrong/right? For example, I heard that dual wielding has no use in real life and let’s not forget about the villains who never seem to run out of bullets.
Poor trigger discipline drives me up a wall. Poor barrel discipline is probably a close second. I’d lump in general gun safety issues, but those two are the biggest offenders.
“Trigger discipline,” is a central rule of gun safety: Do not touch the trigger until you’re ready to fire. Usually you’ll keep your trigger finger straight, or rest it along the frame when you’re not about to fire. In some cases, and depending on your hand, you might rest it against the trigger guard. Regardless, do not touch the trigger until you are sighted in and prepared to fire.
The problem is a generation of directors and photographers have insisted on poor trigger discipline for their films and photo shoots. Often with the justification that, “it looks more dangerous.” Of course, this is because it is significantly more dangerous. It’s a recipe for an accidental discharge.
Barrel discipline is another of these. The safety rule is, “never point the gun at something you don’t intend to shoot.” The full implication extends a bit further than that; you want to maintain awareness of where your gun is pointed at all times, and don’t point it at anything you’re not okay with putting a round into.
I’m a bit touchy about these because I have been around people who didn’t take them seriously. Mercifully, I’ve never seen these go horribly wrong in person, but these are central rules to gun safety for very good reasons. If they’re not respected, there’s a very real danger of a catastrophic accident. I still have a .gif around here of someone playing with a laser sight and accidentally putting a round through his hand, as a bit of schadenfreude.
Related to both is a problem where characters are way too happy to draw their gun, long before its warranted. This is the same reason, it communicates danger to the audience. However, this actively dangerous behavior. It’s reasonable if someone’s going to open fire if they see you, but someone who wouldn’t open fire on someone simply for being there is more likely to start shooting if they think that person is coming to kill them.
Threatening someone with a gun is illegal. It doesn’t matter if the gun’s real, fake, if you really meant it, or if it was a bluff, it’s brandishing, and that is a crime.
I’ll confirm the dual wielding thing for you, it doesn’t work. Modern pistols are two handed weapons. You stabilize the gun with your off-hand. While you can hold one in each hand, the result is going to be messy, and you’re not going to hit what you want. The entire philosophy of, “but I’m firing twice as many bullets,” doesn’t really play because you can’t put those rounds where you want them. Also, trying to manage mismatched pistols is just distracting. If you’ve got different ammo counts, you’re going to be staggering them out or running one dry much faster than the other. Reloading is disproportionately more cumbersome. I get that it looks cool, but it does not work, and is not as fun as it looks.
The other example you’re coming up with is a little more complicated than it sounds, so we’re going to be here for a minute. Also, some of these numbers might be a little off, I haven’t thought about film production in years, so I’m spitballing numbers from memory.
Ammo accounting while filming is hard. The more rounds a weapon loads, the harder it will be for the editor to ensure the weapon isn’t firing beyond its capacity. Especially given that the editor is probably not a firearms expert. They had a consultant on set who can quote off the specs, but it’s unlikely the editor and armorer ever met.
You have a film where the protagonist carves through people with a shotgun before running dry, discarding it, and switching to their sidearm. They have two spare mags for the sidearm, and it carries 15+1 rounds. The shotgun carries 8+1, with a 4 shells in the carrier.
As fights on screen goes: this is a pretty easy set up.
They shoot the initial sequence. Everything goes well, except a squib pack fails to deploy on one of the stunt performers. At this point the pistol hasn’t been used at all, the shotgun’s run through 11 rounds.
The armorer restocks the shotgun, and they shoot the initial sequence again. This time it goes to plan.
The armorer restocks the shotgun, and they collect a set of insert shots. Close ups of hands. The protagonist moving shells from the carrier into the shotgun. The protagonist is filmed dropping the, “empty,” shotgun three times. The second time, the shotgun is scuffed when it lands, and is replaced by another rental of the same make, model, and modifications. (These are called hero props, by the way. If you get a closeup of it, that’s a “hero prop.” If you’re seeing something it wide shots, it might actually be a facsimile. Hollywood uses a lot of plastic guns for scenes where you’ll never get a good look at it, and it’s never fired.) If they have to go back and do some pickups of shots they did earlier, it will now be with a different shotgun, because the first prop has now been visibly altered by that scuff.
Second sequence is shot, this more elaborate, it involves involves a lot of insert shots, a lot of cuts. There’s a wardrobe change midway through, as the protagonist’s jacket is damaged by gunfire. They’re also, “injured,” requiring a makeup change.
The shooting schedule says that everything after the injury was shot last week, along with a couple dialog scenes and some shoe leather for the post fight wrap up, so that’s already done. Everything after the wardrobe change will be done in the afternoon. Wardrobe says they have four copies of the “damaged” jacket on hand. (Same reason you have the extra shotgun: If something happens to one, you need a replacement on hand immediately.)
So, shooting begins. Each of the shots on the schedule for the day have to be done repeatedly. Again, I’m being generous here, but we’ll assume a few go on the first take, and some require a few tries. An easy way to make sure it works as intended is to carve up the shots into the smallest pieces possible, so if something does go wrong it doesn’t cascade out, they can call “cut,” and redo that specific component.
So an individual shot may just be the lead firing a couple rounds, or reloading. One of the henchmen getting shot, taking a dirt nap. Some of this may be arranged by who’s available at the moment, and some of the shooting may get slightly out of sequence if something malfunctions, or they have to swap out props.
Six months later, an editor is handed the film, along all of that chaos. They now have roughly 10 hours of footage, of which they’ll use a few minutes. Remembering they’re not an expert on firearms, they do not know what the handgun can hold, or how many rounds you can put in a pump action shotgun. They now need to construct a coherent fight scene from yards of film that are partially out of sequence, and were shot on different days.
When the film gets to theaters, someone who sits down and carefully counts will note that the protagonist just fired 19 rounds from a SIG P226 without reloading.
This even happens with films that are very careful about this stuff. I may be misremembering, but I could swear there’s a scene in John Wick 2 where he fires 11 shells from a Benelli M4 without reloading. For reference, a military variant of that shotgun will usually carry 7+1.
On the downside, some directors and editors really don’t care. So you won’t have any shots of reloading or the reloading inserts will get dropped by the editor. (“Left on the cutting room floor,” used to be literal, not a figure of speech.) There’s a lot of things that can happen here. I don’t generally hold a grudge about it. “John Woo clips” are their own kind of joke at this point. That said, when you see director and editor who are being careful about this minutiae, it’s always a nice touch.
“Clips,” and, “magazines,” are both correct terminology, however, they’re not interchangeable, and most of the things non-gun users refer to as clips are magazines.
Every repeating firearm will have a magazine. It’s where extra rounds are stored before being loaded into the receiver. In the example of a pump action shotgun, it’s the tube below the barrel which holds shells in reserve. Magazines do not need to be removable, though it is convenient when they are.
A clip is a device which holds lose rounds in place and assists in feeding them into the magazine. On many rifles with integrated (non-removable) magazines, a clip will be used to quickly feed loose rounds.
The easiest rule of thumb is, “if the object mounts into the gun and stays there,” it’s a magazine. “If the bullets are removed, the object is emptied and discarded, during the reload process,” it’s a clip. I can think of a few oddball counter examples to those specific descriptions, but the basic idea is there.
So with that in mind, “John Woo clips,” is technically incorrect, because the weapons in his films used detachable box mags, however, that’s the idiom.
Extremely rare guns will sometimes raise an eyebrow for me. The Pancor Jackhammer comes to mind. It was a fully automatic shotgun developed in the late 80s and has a very distinctive look. That said, it never hit commercial production, and only three prototypes were ever built. At least one of these ended up with a Hollywood Armory, and was rented out extensively in the 90s.
The handheld minigun from Predator and Terminator 2 is a similar situation. There’s one prop, and it keeps getting reused in films. The real M134s are mounted weapons, not handheld.
Conversely, I’ve got a soft spot for the M91, because the gun never existed. A Vancouver gunsmith rigged the thing up in the early 90s to fire blanks. I’m not sure how many were made, but they pop up intermittently, starting in the early 90s.
There’s an inverse example where production companies will simply use standard firearms as advanced sci-fi hardware. I still hold a grudge against the BSG reboot for handing out unaltered Vektor CP1s and FN P90s. Firefly, is another egregious offender here.
In contrast, there’s stuff like the M41a Pulse Rifles in Aliens, which were actually Thompson SMGs, with mounted underbarrel SPAS-12s. Good luck realizing that while watching the film.
Star Wars is infamous for kit bashing existing firearms, and I do really wish people would stop modifying surviving Mauser C96s into “BlasTech DL-44s.” That’s a fairly rare antique they’re destroying. When they could just get a non-firing replica for a fraction of the price. Fun trivia: If you watch carefully, you can actually see the Stormtrooper Blaster Rifles ejecting 9mm shell casings in some scenes from ANH.
I’m not wild about Desert Eagles. They’re simply not worth the price. I get why they’re used in film. It’s a very distinctive looking gun. It’s a very intimidating design. But, it’s not a good weapon, and every time I see someone who’s supposed to be some kind of special operations badass pull one, I’m immediately gone.
Bullets pass through objects. If you’re shooting at someone, and they “take cover,” behind a couch or an interior wall, just shoot through it. Those won’t stop a handgun round. You need solid barriers to protect against gunfire. It will punch through things. Taking cover behind the engine block of a car or the wheels is an option, but hiding behind the body won’t work. The bullet will simply pass through that, and you.
You cannot snipe with a laser at long ranges. Lasers can be useful at very close ranges. If you’re in the same room, it can help you get a bead on where your round will go without having to sight in. However, a laser is still a focused beam of light. It gets wider the further it lands from you. Meaning, as an aim point it loses its value. Second, and more critically, your bullet is a physical object, your laser is a stream of photons. Your bullet is affected by gravity and wind. Meaning, at range, you’ll need to adjust for bullet drop. It is not as simple as lining up the crosshairs and pulling the trigger. At extreme ranges (over a mile) it gets really complicated. Short version, a sniper with a laser gets nothing from it, except the ability to inform their victim a bullet’s about to hit.
Suppressors do not silence a weapon. They can significantly reduce the sound from a gunshot, but it’s still going to make a lot of noise. The sound of the gunshot is the rapidly expanding, burning gasses. If you could fully capture those, you would dramatically reduce the noise a gun makes. This is somewhat possible with purpose built firearms designed to be as silent as possible, however it takes a lot more than just screwing a can on the end of your barrel. Suppressors do let you fire a gun without alerting the whole block, but everyone the immediate area will still hear the (quieter) gunshots.
Related bit, threaded barrels on firearms are a little unusual. Most commercially available guns in the US cannot mount a suppressor without modification. Variants with threaded barrels do exist (for many), though getting access to those will take extra work.
When it comes to silencing a firearm, the magic number is 343m/s. If your bullet is traveling faster than that, it is faster than sound, and the bullet will create an audible crack as it travels. This is, literally, a mini-sonic boom and the only way to prevent it is to keep the initial velocity under that. Incidentally, if you’re using a modern 9mm pistol, your muzzle velocity will be at least 360m/s, unless you’re using subsonic ammo.
“Gangsta Style,” shooting, where the the gun is held horizontally, doesn’t work. You can’t hit anything. You need to be able to use the sights of your weapon.
Do not close your opposite eye while aiming. You might squint a bit, but you need that eye to help judge distance, and improve awareness. This might not hold true when you’re firing a .50 into an adjacent zip code, but, 99% of the time, keep it open.
Magazines aren’t disposable. Those are actually fairly expensive ($15-$20 USD on the low end for common magazine types.) You really don’t want to just drop them on the ground and forget about them. You want to swap a partial mag for a fresh one, depositing the partial in a convenient pocket, pouch, or whatever. Restack your mags when you have time, after the shooting is over.
Related to that, you don’t want to run a gun dry. Reload when you have a moment and are starting to run low, not after it’s empty. The only time you want to empty your gun is when you’re doing practice shooting on the range. The last thing you want to is drop a hammer an empty chamber when someone’s trying to kill you.
Firearms magazines aren’t cross compatible between weapons, except when they are. Handgun mags are, very rarely cross compatible. If a weapon is built to a specific pattern, like the Beretta 92/M9 knock offs, Then magazines built for that pattern should be compatible with other pistols of the same pattern. The entire point is to allow multiple manufacturers to supply military contracts.
There’s one major exception with handguns: Glocks are very cross compatible. If the magazine is sized for the correct cartridge, you can cross load any magazine from a larger, compatible Glock. For example, the Glock 26 is a subcompact 9mm. It will accept magazines from the full frame 9mm (the Glock 17), the compact 9mm (the Glock 19), and (I assume) a few of the more recent 9mm variants like the Glock 46. Conversely, your Glock 17 can not load any of the smaller magazines.
When it comes to assault rifles, there’s a couple standards, and a lot of rifles that aren’t interested. In the early 80s, NATO adopted the STANAG format. This isn’t a single magazine type, it’s standards on how the magazine should interface with the weapon, so that they are cross compatible. The entire idea behind NATO was transnational joint operations, and the STANAG was adopted along side the selection of 5.56mm as the standard assault rifle cartridge. Having a shared magazine format would make logistics easier to manage in situations where multiple armed forces were operating together. The Warsaw Pact had a similar standard, it’s used in the AK, though I’m unaware of what the formal name is.
Ammunition names are more than a little idiosyncratic. Generally speaking there are three different conflicting measurement systems.
Metric is the simplest, this is the diameter of the projectile, expressed in millimetres. Sometimes this comes with a qualifier, or with the length also expressed. So, 9mm Parabellum and 9x19mm are the same round. This is often abbreviated to 9mm without qualification, but that’s actually a problem, there a lot of common 9mm cartridges. So, 9×19, which is “the standard” 9mm cartridge you’d think of. There’s 9mm Makarov (9×18) which was the Warsaw Pact 9mm pistol round, there’s .380 (9×17), there’s .357 Magnum (9x32mm though you’ll rarely see the metric measurement for this one.) If it’s a .38 (including the .357 family), it’s a 9mm round.
Caliber is where the wheels come off. In theory, the caliber is the diameter of the bullet in hundredths of an inch. In practice, it sometimes adjusts that value as a ratio against the length of the cartridge. This is probably why a .38 and a .357 are both the same size, even though the .38 should be significantly larger if it were just hundredths of an inch. (And, unless my math skills are worse than usual, 9mm should work out to around .36, so probably .357, meaning the .38 is the one messing with us here.) I say, “probably,” because sometimes the caliber changes on a whim. The .30-06 comes to mind. It’s a .30 round but the “06” refers to 1906.
Gauge is used exclusively for shotguns, and this one is a really goofy measurement system. The size of the bore is calculated based on a lead sphere weighing one pound divided by the gauge. So, a 12 gauge is the diameter of a lead sphere weighing 1/12th lb. So, a 12 gauge has a bore diameter of 18.53mm (and yes, I had to look that up.) This means, as the gauge goes down, the size goes up. It also means looking a metric measurements for shotguns is really messy.
If that’s not confusing enough, there’s also one shotgun shell (the .410) which uses a caliber instead of a gauge. It’s also the smallest commercial shotgun shell.
While we’re on the subject of shotguns, it’s worth noting these things have a lot of range to them. This is very dependent on the individual shotgun, but figure a “normal” 12 gauge pump loaded with buck will have a six foot spread at 100 yards. There’s two implications to this. First, it kill someone at 100 yards. Second, you need to aim. It’s not a scatter gun that will paint everything in the room.
There’s also a very specific consideration with shotguns, slugs or shot. A shotgun can put a monstrous slug down range, and if you have rifling, that’s going to be fairly accurate, and lethal, beyond handgun range. Shotguns are a little weird here, because there’s multiple roads to rifling. You can have a rifled barrel, you can have rifled slugs, or you can have a rifled choke. Firing shot down a rifled barrel will widen your cone (not sure exactly how much, I haven’t done this personally.) If it’s a slug, you want to make sure you’re getting rifling somewhere, or the slug will tumble in flight, and your accuracy will suffer.
I’m not sure when this transitioned from a list of gripes to a firearms primer, but here we are. I hope you enjoyed.
