Colt:
(l) Both ends of the barrel were tightly corked and the pistol was exposed for one minute, in a box prepared for the purpose, to a bast of fine sand, the magazine being empty. A representative of the company removed the surplus sand by blowing, jarring and wiping the piece with the bare hand only. Time required to fire 7 shots was 1 minute and 56 seconds, using the arm as a self-loader. Seven more shots were then similarly fired.
(m) The above test was then repeated, except thatt the arm contained a loaded magazine when exposed to dust. Time required to fire 7 shots was 53 seconds, using the arm as a self-loader. Seven more shots were then similarly fired.
NOTE - After this test part of the sear was found broken and a new sear was inserted.
