 At the request of Lieutenant Colonel William S. Harney of the Second Dragoon Regiment, Colt traveled to Florida with 100 Ring Lever rifles for the review.During the trial, officers of the second dragoons reported favorably on Colt's rifles after they conducted several experiments that demonstrated that the First Model Ring Lever rifle was equal or superior to conventional arms in accuracy, penetration, rapidity of fire, resistance to weather, and safety.The experiments found that the Ring Lever rifle could fire off sixteen shots in thirty-one seconds, with the ability to load and fire an eight-shot cylinder in forty-eight seconds.
