Small-Scale Question Sunday for April 19, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I'd guess it's cut-down AK "pistols".

I've seen people one-hand an RPK-74 when shooting into the air, but 7.62x39 has 1.5 the energy of 5.45x39. I doubt anyone would want to shoot that from a pistol.

1.5x the energy

Recoil is based solely on momentum, not energy; energy is not conserved in explosions. m(bullet) * v(bullet) = m(rifle) * v(rifle).

Accounting for similar impulse (since the bullet spends about the same amount of time in the barrel for each of these), here's what we see:

7.62x39 out of a Draco is 124 grains * 1700 FPS, and a Draco weighs about 7 pounds (or 49000 grains), so if you let the rifle freely recoil it'd hit you at 4.3 FPS. Oh yeah, and that's after the action's done cycling; the peak impulse is only going to be about 6/7ths of that because there's about a pound of mass that takes a while to hit the back of the assembly.

Compare to-spec .357 Magnum out of a typical pistol, which is 158 grains * 1400 FPS, and the gun weighs about 3 pounds (or 21000 grains), so if you let the handgun freely recoil it'd hit you at 10.5 FPS.

This is why Dracos are manageable one-handed from a pistol; but the fact you're holding 7 pounds out in front of you makes them kind of unwieldly.

TIL, thanks

They exist. Tokarev is a niche handgun for collectors in the USA. Handguns chambered in rifle cartridges appeal to gun nuts for some reason, IDK why, but you can easily find both AK caliber and AR-15 caliber handguns.

There are 3 reasons why:

  • it's an end run around the 1989 Federal import ban of "non-sporting" rifles (pistols are not rifles), which in addition to AKs also tends to affect clones of HK products, particularly MP5s
  • it's an end run around SBR laws, especially after the advent of the "pistol brace" (it's a stock with a fig leaf over it); yes, the lack of tax and registration is part of it, but there are a bunch of other rules around SBRs that don't apply to pistols
  • because rifles that short are kind of stupid and impractical, and memes are a great reason to own guns (usually Dracos and TEC-9s, but also applies to AR-18s around St. Patrick's day, Carcanos around President's Day, FALs in certain paint jobs, etc.)

the "pistols" in question are essentially AKSU-style carbines with no stock installed. I'm given to understand they're fairly popular.

New "handguns" (PCCs? SMGs?) currently available for purchase on guns.com:

  • 7.62×39 Soviet: 130

  • 7.62×51 NATO: 6

  • 7.62×25 Tokarev: 2

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
