The Kahr recoil springs are designed so the the front is open for freedom of movement, but the rear is closed to grip the recoil guide rod and stay in place. Turning the spring the wrong way can allow the open end of the spring to override the rear of the guide rod and jam your your pistol... not nice if your life is at risk!
I had problems with the Fiocci 170-grain FMJ cases having too pronounced a case mouth that would catch in the chamber.
Check out the video at the 3:15 point for the recoil assembly:
