Although this does not sit well with the early 1900's purchase of the design for Colt and Steyr trials. In each case, several field tests were conducted from 1907 to 1911 to decide between the Savage and Colt models.
One of Colt's most successful areas was the 1910 test conducted by its designer, John Browning. About 6000 shots were fired from one pistol in two days. The gun started to heat up and was kept submerged in water to cool it down. The Colt rifle passed without problems, while the Savage design had 37.
