A double action revolver used as a single action when your hands are being a pain?
Autoloaders are the easiest to hold and shoot, though.
There's lots of ways to rack a slide without straining your hands.
Like adding a slide racker-rear sight replacement.

These are designed for guns with optic sights, but can be welded to regular open sights, too.
Or just be crude about it, and push the front sight/top of the slide against a table top.
Fingers off the trigger, of course.
