This is a single barreled gun that reloads from a tubular magazine when the user slides a grip towards and then away from themselves. Pumpactions are popular with casual shooters in the US. It is far less common in Europe. The pumpaction is inherently slower than all but the single barrel break action and thus follow up shots are more difficult. In addition to this they have the mechanical complexity similar to the semiautomatic but lacks the recoil reduction.
