It's older, but I always had a + impression of a episode of the ABC sitcom; Doogie Howser MD.
Doogie(played by actor Neil Patrick Harris of the hit show;
How I met Your Mother) was a young doctor/med student. After a violent crime, he decides to get a pistol for defense.
The TV series could have trashed the gun industry or portrayed the gun shop staff in a - way, like a few film & TV shows do,
.
The show instead had a FFL holder/gun shop manager who was polite, professional & explained to Doogie why gun safety/security is so important. He taught Doogie the basics & wasn't pushy or macho.
It was a good image of gun owners & those sales clerks who act like mature adults.
