I read it as he’s performing a press check in preparation for shooting the person next to him.

Presumably, Bond did a bunch of shooting to get to the point where the comic starts. The gun is potentially dirty enough where failure to feed or extract may be happening. A simple push of the slide back enough to verify that he’s got a live round chambered might save him from having to resort to other methods to silence the other person in the comic.

They just can’t get enough

Enough to be covered in entrails, providing a nice segue to an encore performance of Shake It Off.

Thanks but i prefer it my way
