Within firearms, chamber pressure is the pressure exerted by a cartridge case's outside walls on the inside of a firearm's chamber when the cartridge is fired. The SI unit for chamber pressure is the megapascal (MPa), while the American SAAMI uses the pound per square inch (psi, symbol lbf/in 2) and the European CIP uses bar (1 bar is equal to 0.1 MPa).
C.I.P. uses a drilled case to expose the pressure transducer directly to propellant gases. The piezo measuring device (transducer) is positioned at a distance of 25 millimetres (0.98 in) from the breech face when the length of the cartridge case permits that, including limits.
Underwood Ammo offers three 9×25mm Dillon factory ammunition loads from 90 to 125 grains. [6] Conversions: Drop-in barrels are available as aftermarket parts for the Glock 40, Glock 20 and Glock 29 semi-automatic pistols. [7] These pistols are originally chambered by Glock for parent cartridge of the 9×25mm Dillon, the 10mm Auto.
This is a list of firearm cartridges that have bullets in the 9 millimeters (0.35 in) to 9.99 millimeters (0.393 in) caliber range.. Case length refers to the round case length.
9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...
In the classic division a choice can be made between up to a 10-shot capacity 1911 with minor scoring (e.g. 9×19mm) or up to an eight-shot capacity 1911 with major scoring (e.g. .40 S&W or .45 ACP). In the revolver division major scoring can be achieved with a 9 mm bullet diameter, but with a power factor of 170.
This is not a significant design problem as the recoil forces are directly comparable to those of the .45 ACP, and the lock-up between the barrel and slide is normally more than adequate to handle the increased pressure. The barrel must certainly be strong enough for the increased pressure but modern metallurgy makes that simple enough.
Another difference between the C-9 and C-9 Comp. is the barrel length. Its 4 in (102 mm) barrel is 1 ⁄ 2 in (12.7 mm) longer than its sister weapon's providing for better accuracy and balance. The compensator and extra bulk also increase the weight.
