The other night my boyfriend made me watch The Dark Tower: The Gunslinger because I had never seen it and I love Steven King’s books. I hadn’t read this one either - it was actually pretty good!
In the movie, the Gunslinger had revolvers made from Excaliber and they showed how fast he could reload them! It was impressive although definitely high speed/CGI for him to reload that quickly.
Later he gets a belt that has ammo set up for the revolver and he just has to spin the revolver around under the belt and it’s like the belt automatically loads the revolver. I wish they made that in real life!
