This list contains manga that I've personally read and love.
The reason there might not be hundreds of action manga here is because i either did not like the manga and didn't want to recommend something i did not like or because i simply haven't read them yet.
Take your time and i hope you like these manga that i recommend for you!
You may feel your favorite manga should be gathered together into distinct categories for your own reference and, now, you can do this with a LIST. After you've created your list or lists, you can proudly recommend them to other manga fans to showcase and share your taste in manga.
