Silencers: Outside Hollywood Movies, Not Everything Can Be ‘Silenced’

Silencers. Yes, today our visiting expert, Piper Bayard from the writing duo Bayard & Holmes is here to do some myth-busting. The movie industry seems to believe one can use a silencer on everything.

***Yet another peeve for many who are even remotely knowledgable about the gun world and how things actually work.

I get that fiction is supposed to be over the top, especially with spies and thrillers. It doesn’t matter that most spies actually do boring office work and are usually as ‘sexy’ as our 6th grade librarian. Hollywood doesn’t care that most intelligence operatives and assassins are more likely to drive a Mazda than a Maserati.

In reality, drawing a lot of attention and being SUPER memorable is a BAD thing.

This said, we don’t care when it comes to fantasy. Spies and assassins are sexy in fiction. And it is TOTALLY possible to hold onto a bullet train traveling at up to 200 miles an hour….in fiction.

So how can we keep our fiction imaginative, over-the-top and sexy AND gain at least a modicum of respect from those who are savvy about this topic? *drum roll* Well this THURSDAY y’all can take my class The Edge: How to Write Mystery, Suspense & Thriller (sigh up HERE). This is a TWO-HOUR class and obviously we can go into a lot of detail. You also get a free recording, which is super handy.

For the moment though? Here’s a quick fix to help you maintain the magic without blowing your cover credibility.

Take it away, Piper!

Silencer Movie Magic

Movies and books do absolute magic with firearms and their targets! Sniper rifles fire with a whisper, bodies silently crumple to the ground, assassins shoot successive shots from silenced pistols without a hiccup, and all other manner of . . . fictions.

In our last post, Firearms: The Writer’s Guide to “Knowing Your Weapon! we looked at the various types of firearms espionage and crime characters might use and took a bit of the fiction out of fiction. Now let’s turn our attention to silencers and what cannot be silenced. For simplicity’s sake, we will use the terms “suppressor” and “silencer” interchangeably.

The purpose of silencers in the field is to keep anyone from recognizing the sound of a gunshot and screaming, calling 911, or returning fire.

In most cases, the shooter doesn’t care if someone hears the shot as long as they don’t recognize it as a shot. People will normally ignore noises that they hear but don’t associate with gunshots or other dangers. Because of this human tendency, the level of “silencing” our characters need with their firearms depends on their situations.

For example, if a character intends to walk into a functioning steel mill and shoot someone, they don’t need much in the way of silencing. On the other hand, if they want to shoot someone in a library without being noticed, they will want the best silencing available.

So how do we attain maximum silencing?

We’ve all seen characters with cylindrical silencers screwed onto the barrels of pistols which, in fiction, range in size from a Saturday night special to Dirty Harry’s .44 Magnum. Then they fire with a pftzzz so quiet that it wouldn’t wake a drowsy guard dog. But a silencer on the barrel is only the first step. For maximum silencing, one must also consider the things that cannot be silenced.

A Silencer Can’t Quiet a Slide

Suppressors can be used on revolvers, but with much less effect than can be achieved with a semiautomatic pistol; therefore, a shooter would most usually use a semiautomatic handgun. (See Firearms: Know Your Weapon!) Semiautomatic pistols have a slide along the top.

This pictured .40 Smith & Wesson has the slide locked open. Note the round in the chamber. The slide comes back when a shot is fired. The spent brass is ejected, another round is fed in, and the slide comes forward, readying the pistol for the next shot.

This motion of the slide can’t be silenced.

So what is a shooter to do?

When it comes to dealing with slides, size matters, so let’s talk about size for a moment.

Ever wonder why Bond always uses the Walther PPK .380 in the field? It’s not just because it’s cute and German. It’s because the .380 semiautomatic provides enough energy for close-up assassination while still being capable of effective and inexpensive silencing.

In fact, the only more powerful mass-produced auto-loading weapon that can be efficiently and cheaply silenced is the Russian knockoff of the Walther PPK, the Makarov .380, which is like a regular .380 on steroids.

With a bullet slightly wider and heavier than that of the standard .380, the Makarov has the maximum energy of any subsonic cartridge that the Soviet firearms specialists could put into a straight blowback semiautomatic design.

***We’ll get back to that “subsonic” part in a moment.

The other benefit of the .380 is that it has a straight blowback design, unlike larger handguns. With the straight blowback design, the pistol can be modified to manually lock the slide in a closed position so the weapon can fire without causing the rounds to jam. The locked slide prevents the noise of the slide operation along with the sound that escapes the ejection port when the pistol cycles.

The slide of a semiautomatic cannot be silenced except by locking it in place.

So you might be wondering at this point how anyone gets to fire a second shot if the slide is locked in place.

To fire successive shots in real life, a shooter of a silenced pistol must manually unlock the slide, cycle out the cartridge, and then re-lock the slide. Locking and unlocking is accomplished with a small lever that would resemble the safety lever on a slide. With a bit of practice, a pro can operate it in approximately one second without much effort.

While a pistol with a manual slide lock does not allow for the quickest successive shots, it can be quite discreet, making it ideal for some situations.

For example:

if the shooter intends to assassinate an individual who is walking home on his usual route after work, the shooter could get a close-up head shot on a side street, and someone walking twenty yards ahead of the target would not notice it.

Another example is if the shooter catches the target alone in their hotel room, home, or office. In such circumstances, a trained assassin could easily take the time to deliver a second “insurance” shot on a high-value target without a hotel maid in the hallway or people in the next room hearing anything.

Writing Tip Regarding Silencers:

One danger to silencing properly with a handgun is that the shooter will forget to lock the slide after cycling in the second round. The weapon will still be suppressed, but it will still make more noise than it would if the slide were locked. If you need a character to make a mistake while firing with a silencer, this is a logical one to make.

The Sonic Boom

Note the emphasis on the word “subsonic” in the section above. That’s because the crack of a bullet breaking the sound barrier is impossible to silence. That is true no matter what firearm or suppression equipment is used. As a result, for the maximum silencing, it is important to use subsonic cartridges.

The Falling Brass

The sound of falling brass is also impossible to silence. Only shooters in movies don’t have to worry about that ping of flying brass hitting objects or the floor. To prevent the brass from falling, shooters can carry specially designed brass catchers that they can attach to the pistols.

However, the act of attaching them can slow down a shooter. Also, the catcher, itself, is one more piece of evidence that can be found on a shooter, and less evidence is always better.

A more down-and-dirty trick, so to speak, is to use a sock as a brass catcher. However, there are three problems with this method. First, it blows out the end of the sock, which could lead to the brass falling anyway. Second, the sock could catch in the slide and jam it. And third, the sock covered in gunpowder and residue is one more piece of evidence. So as a general rule, most professionals risk the sound of falling brass.

But isn’t the brass evidence?

Not so much as one might think. That’s because an intelligent professional uses “clean brass.” Clean brass is brass that would not be identified to the country of origin, and it would have no fingerprints, so the shooter doesn’t have to worry about leaving it behind.

The Falling Body

The third thing that cannot be silenced is the sound of a falling body. Dead bodies drop, and they aren’t always conveniently located in an open space with a thick carpet. They can smash into furniture and knock things over. They can break glass and thump into floors and walls. If in a bathroom and the body falls against a cast-iron tub, it makes a loud, heavy ringing sound.

Catching a body to prevent the noise of the fall poses the equally risky problem of the shooter being covered in blood. Bloody people tend to have trouble blending in when walking out of a building or down a street. It’s just an inconvenient truth that bodies fall where they die.

Writing Tip:

An assassin’s inconvenient truth is an author’s plot line. While you could have dead bodies collapse in neat little heaps on a shag rug, you could also use them to punch up your plot. Get creative. Let them break things, tip out of windows, fall onto hot stoves, or even create a domino effect that leads to widespread disaster on the set. You’re not likely to go too far with it.

Bottom Line about Silencers:

Three things cannot be silenced—the shells being ejected, the crack of the sound barrier, and the drop of a falling body. Which brings us to the fourth thing that cannot be silenced—the savvy reader who sends angry e-mails if an author gets this wrong.

  1. Awesome post, Piper! I am quite the noob at writing about guns (I’ve never even held one) and don’t really use them much in my stories, but I read/watch a lot of mysteries. In one Columbo episode, the bad guy used a feather pillow in front of his gun as a silencer when he fired (this was on a vacation cruise, with tiny cabins right next to each other, so silence would have been crucial). Is this feasible, or another instance of Hollywood poetic license? Thx!

    1. I didn’t realize that, Kathy! I’m a military kid, so we were on the range before we hit double-digits.

      BTW, this is a great question. 🙂

    2. Great question. It can help, and in a pinch it is better than nothing. It can also start a fire and/or cause the pistol to malfunction on the next shot, depending on how you hold the pillow.

      1. Wow, LOL! Now that’s an episode I would have watched…. 😉

    I own and play with a few different types of silencers, and this is really spot on. Rifle silencers don’t make the cool pfft sound that Hollywood dubs over them, nor do 99% of the pistol silencers. Consider that a highly efficient silencer will only bring down the initial blast down 32-35 decibels. Most falling in the realm of about 27 Db of sound reduction. Meaning you very much hear the shot. What is an interesting phenomena, is that if your standing 400 ft away, you’d notice a funny gunshot kind of like a super loud airgun, where you think the direction of where the sound is coming from is one place and in fact it is not. It’s also a very nice flash suppression device. I’ve also seen movies and video games where the characters are trying to explain things. I wish they wouldn’t. No, it’s not slowing the bullet down at all, at least in the vast majority of designs. What you are doing is adding a “combustion chamber” to the end of the barrel that is allowing the burning of any remaining powder, and providing a slight increase of pressure which accelerates the bullet more (though slight). What’s happening is that the high pressure gasses are being slowed down as they pass through the baffles, whose design allows for a slower dissipation of pressure. It’s all fascinating physics. Oh, and the originator of the silencer was Maxim, the same father and son that brought us the belt fed machine gun. They applied that design to automobiles as a “muffler”. And now you know. 😉

    1. Holmes says thank you. He did not know Maxim originated the silencer or that the design was applied to mufflers. We love learning from our readers.

  2. Bodies don’t ‘crumble to the ground’. Crumple, maybe…

    1. Thank you for catching the typo.

      1. I guess. I can’t find it.

      2. It was just an amusing image. Obviously a typo. But it would make body disposal so much easier… 😉
        A very interesting and informative post! Much enjoyed.

        1. Oh NOW I see it! You get blog blindness when you’ve read the same thing over and over and neither of us could find it, LOL. I guess if you hit them with a flame thrower? Thanks for the catch and the tip 😉

    2. I thought you caught a typo which, btw (always appreciated). But since I found no ‘crumbling bodies’ I am assuming you are giving a tip and YES! Unless your character just hit someone with nitro glycerin they will crumple not CRUMBLE. I have the same peeve with ‘He hung himself.” NO, clothes are hung and people are HANGED. Apologies for the confusion. But, on the off chance I DO have a crumbling body in the post, lemme know because I can’t find it. Must be in REALLY tiny pieces, 😛

      1. It is in the first paragraph of Piper’s post. Just a typo, but a fun image. Death ray, anyone? 😉

    Makes notes, always shoot someone in the steel mill (or in the local sports park, where everyone knows there’s a shooting range already).

    1. LOL. Exactly.

I LOVE hearing your thoughts!
