Looking for MMCs that use guns not magic

The title says it all. I am looking for suggestions that lean into guns over swords and magic. I am generally burned out on magic users at this point and wouldn't mind reading something different. I know there are a lot of books and I hope for a big list. I also listen to books more than I read. Setting can be anything from sci Fi to fantasy to post apocalypse. So in short this is a gem hunt. Let's see what is recommended.
