You’re not looking for a job in sales, are you?
This kind of nonsense reminds me of the P&R Medusa revolver that “fired 27 calibers.” Among other things, it fired 9mm Luger, 9mm x 19, and 9mm Parabellum. It also fired .380, 9mm x 17, and 9mm Kurz.
Uh - huh.
Did you know that your Walther PPK/S will also fire 9mm Corto and 9mm Short?
Amazing!!! One pistol that shoots five calibers!
