 company, who after a year of development produced a military version of the weapon.

A demonstration to officers at the United States Navy yard in 1875 was successful, however they recommended that Pratt and Whitney continue with development of the system, incorporating improvements to the feed system, which were designed by E.G. Parkhurst, an engineer at Pratt and Whitney. The army attended the tests, but showed no interest in the weapon.

Parkhurst added many improvements to the gun's firing mechanism which made it more reliable. During 1877 additional tests took place with a .45 calibre (11.4 mm) version of the weapon, which determined its muzzle velocity to be 1,280 feet per second (390 m/s).

On 17 June 1879 a further demonstration was carried out at the Navy Yard, during which the weapon was presented by Francis A. Pratt

. The weapon fired a total of 10,000 rounds during the test, taking a total elapsed time of 27 minutes 36 seconds, with breaks between firing to resolve an issue with one of the extractors. While the test was not without issues the weapon managed to fire 4,722 rounds before the first stoppage , and after the stoppage was resolved it fired approximately 5,000 rounds without incident.

On 15 January and 17 March 1880 duplicate tests were conducted at Sandy Hook

The Admiralty were so impressed by the demonstrations that they adopted the weapon and purchased the rights to produce it in England. Gardner would remain in England to supervise the construction of the weapons.

 then took an interest in machine guns and after a series of trials selected the Gardner gun. During these tests a five-barrelled Gardner gun fired 16,754 rounds before a failure occurred, with only 24 stoppages. When operator-induced errors were taken into account, there were only 4 malfunctions in 10,000 rounds fired. The Army adopted the weapon, although its introduction was delayed because of opposition from the Royal Artillery
