The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]

Models in use included the M1911A1 (Colt .45 Automatic), Smith & Wesson (Combat Masterpiece in .38 Special caliber), Smith and Wesson Model 1917 (.45 ACP and .45 Auto Rim) and various other small ...
We can then derive a conversion table to convert values expressed for one percentile level, to another. [ 5 ] [ 6 ] Said conversion table, giving the coefficients α {\displaystyle \alpha } to convert X {\displaystyle X} into Y = α .
The military has distributed more than 100,000 M17 and M18 handguns, the latest in a long line of sidearms that US troops have carried into battle.
The velocity was 816.8 ft/s (249.0 m/s) and penetrated ten of the 0.5 in (13 mm) boards, spaced 1 in (25 mm) apart at 25 ft (7.6 m). Bullets weighed 200 gr (13 g) grains with steel envelope and 4.7 gr (0.30 g) of smokeless powder. Conclusions were that it was a handy and well balanced pistol with good certainty of action.

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.
The above proof round pressure requirements for the 9 mm and 12.7 mm rounds established by the British Ministry of Defence are higher than the current (2008) C.I.P. proof round pressure requirement legislation for the civilian equivalent 9 mm Parabellum (C.I.P. P max rating 235 MPA / (34,083 psi) and .50 Browning (C.I.P. P max rating 370 MPA ...
