Main article: Blowback (arms)
In "blowback" operation, the bolt is not mechanically locked at the moment of firing. The bolt is relatively massive and is kept forward by spring tension alone. This simple design is mainly seen in firearms designed around relatively low-power cartridges, where spring tension and the mass of the bolt (or slide) are sufficient to keep the bolt forward until chamber pressures have receded to a safe level.
