Although neither the First nor Second Model Ring Lever rifles saw widespread adoption by any military organization, several were procured by the United States Army and the Texas Navy. After an unfavorable review by Army officials in September 1837, which reported that Colt's First Model Ring Lever rifle was prone to failure and too complicated for combat service, a second review was conducted in March 1838. 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. This board of officers advocated equipping select trained men in each company with Colt's rifle, fearing universal employment may cause damage to the guns because of their delicate construction. As the board was conducting its experiments, several friendly Indians had gathered to watch and described Colt's rifle as "great medicine." With the success of the tests, Army Bvt. Major General Thomas Jesup agreed to outfit a section of the second dragoons with fifty First Model rifles for use during the Second Seminole War. The purchase gave Colt a total of $6,250, or $125 per rifle.
