(Hilarious Trope) That's not how this gun works!

EDIT: Just so you know, I might have been wrong about the 3rd example!

1. The Simpsons (Season 30, Episode 9) - The character is holding a revolver (which is normally charged by putting the bullets inside the cylinder) and charging it by putting a magazine in the grip like a Glock. Please note that this was done intentionally to make fun of how guns are portrayed unrealistically in movies;
2. Shadow the Hedgehog video game - In one of the trailers, Shadow is holding what I think was an M4A1 and, in this shot, he is arming it by pulling the handguard like a shotgun. The handguard is only for protecting the shooter from the heat generated by the barrel.
3. Stranger Things (Season 5, Episode 8) - During the fight with the Mindflayer, Nancy is loading an M4A1-5, and, after she inserts a magazine, she is pushing the carrying handle to arm it like a shotgun. That's not what a carrying handle is for, obviously.

I want to mention that I know there's another popular example with a silencer for a shotgun or something, but I am not familiar with it. Also, I tried my best to identify each gun, so please correct me if I was wrong about any of them.

Honorable mention - "DC-34 Automatic shotgun, there is only 3 of them in the world" that Batman turned into non-lethal version that shoots small Batarangs...it's just KSG 12

Honestly the "deadliest (somehow) shotgun ever" that got turned into "nonlethal (some fucking how) version" is the only thing in the ENTIRE absolute batman that made me say "bullshit"
