SUBSTANCE: trigger mechanism comprises a trigger device having a trigger arm with the first trigger surface and a firing member having a main body with the second trigger surface and an interacting portion for interaction with the firing mechanism to drive the firing mechanism. The trigger also includes a roller arranged to prevent falling out and to interact with the first and second trigger surfaces. The trigger device is rotatable between a loaded position in which the roller is held between the first and second trigger surfaces and a free position in which the second trigger surface is withdrawn from engagement with the roller and the firing member is released. The firing member is rotatable between the first position in which the shooting member is held by the roller and the second position in which the firing member is withdrawn from interaction with the roller.
