(Finals is like an extra portion for the top few competitors. Your score in finals is added and that's your total. It was added to make the sport more spectator friendly. When I shot it was just 10 extra shots but shortly after I stopped it was changed to top 8 shooting one shot at a time and lowest shot gets eliminated. I believe this is still the case based on pictures I saw of the two finalists shooting side by side alone.)

~~So it's possible he won silver as individual and the team didn't win or also got silver. I haven't actually looked into the Olympic rules or results but that's how it was when I shot competitively.~~

Edit: Looks like 10 meter air pistol categories individual men, individual women, and mixed team are all run at different times. So it was only as a team that they won silver. I don't know about the individual results of the team competition, but regardless it wouldn't have earned a medal. https://en.wikipedia.org/wiki/Shooting_at_the_2024_Summer_Olympics
