Thompson–LaGarde Tests
The Thompson–LaGarde Tests were a series of tests conducted in 1904 to determine which caliber should be used in American military handguns. == History == The Army had previously been using the .38 Long Colt, and the cartridge's relatively poor ballistics were highlighted during the Philippine–American War of 1899–1902, when reports from U.S. Army officers were received regarding the .38 bullet's inability to stop charges of frenzied Moro juramentados in the Moro Rebellion, even at extremely close ranges.
