That tool is useful if your barrel is screwed to the receiver.
Many other guns, like for instance the one that I use at the range (a reproduction of a LE PAGE pictured below) have different and surely more practical locking systems.

Nope. That's for loading the pistol, not cleaning.

It's a two part barrel that unscrews at the chamber area. You just put the powder and the ball on the chamber and then screw back the barrel. No hammering of the ball down the barrel needed.
