The Definition of Blowback
A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired.
In such case the breechblock immediately begins to separate from the barrel upon firing.
Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber,
are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.
