Kind of a fast action rock paper scissors we call shoot-load-shield. Maybe people called it 007

Two players face each other, tap twice in their lap or on a table with both hands, then have to choose an action:

Load - point thumbs over your shoulder. This loads your weapon

Shoot - make double pistol hands toward your opponent. This fires your weapon

Shield - crossed arms in front of your chest. This blocks your opponents shot.

You have to load before you can shoot, and if you shoot you have to reload. Most people load first round since you are both unloaded to begin with.

To incentivize not just shielding every turn, you can play with the rule that if you load six rounds without shooting, you get a shield penetrating bullet. But we rarely did that because people would shoot just for fun anyway.

Here's a video of kids learning to play. Skip to about a minute to see it in full action. We play much faster: https://youtu.be/rNugwEOZ3JE?si=oqoDETuUVdQvG4vh

Side note: looking for a video, a kid had made a tutorial that added "reflector" that bounces your opponent's shot back. I like that idea if you have to reload the reflector, too
