Smith & Wesson invented and patented the half-moon clip, but at the request of the Army allowed Colt to also use the design free of charge in their own version of the M1917 revolver. After the war, Naomi Alan, an engineer employed by Smith & Wesson, developed a 6-round full-moon clip.

This feat was possible by using moon clips to allow quick and reliable ejection of the fired rounds, and a quick reload of all six chambers at once.

However, many civilian shooters disliked and still dislike using moon clips. Although full moon clips allow a revolver to be very quickly reloaded, loading and unloading the clips is tedious, and bent clips can bind the cylinder and cause misfires.
