[nq:1]I know the term "blowback" originated in the CIA, but does anybody know when and wherher it is arributed to a particular person. [/nq] The term probably originated long before the CIA. It refers to, among other things, an automatic or semi-automatic firearm mechanism operated by recoil, rather than by the gas from the cartridge.

  • Blowback actions have been around for a century or so, though I don't know when that term came along.
  • "Blowback" can also mean "rearward escape of powder or primer gasses from the chamber around the bolt or breechblock caused by a split or fractured cartridge case or a punctured primer" (), which may be where the CIA sense came from.

No, blowback systems and gas systems are different. The .30 M1 was a gas system, while the .45 M1911 was blowback.
