In older movies (pre-90's), many gun fight scenes have cartoon sounds. I can almost imagine the scene drawn and the words KAPOING, POW, ZOINK being shown. Here's an example from 007.

In more recent movies, the sound is of course more realistic.

Now, I get that older movies didn't have the same audio range we have today (punches sounded like slaps!), but old gunfights sounded ridiculous with these cartoon sounds. They could have made high-pitch shots to account for TV speaker properties, they didn't need to exaggerate like this.

What was the main reason older movie gun fights sound so cartoonish, weird, and unrealistic?

You can find examples like in movies from the 90's as well, but they're more rare. In recent movies, the sound is of course more realistic.
