The invention relates to a method and a device for the quality control of a rotationally symmetrical body (2, 2, 2″) and a grip (4) of a handling system (5) for gripping a rotationally symmetrical body (2, 2, 2″). The aim of the invention is to improve the quality control of rotationally symmetrical bodies (2, 2, 2″) in such a way that it is faster, reliable and more economical. To this end, the grip (4) comprises grip fingers (26) having rotationally symmetrically holding elements (29, 31) for holding the body (2, 2, 2″), the holding elements (31) being mounted in the grip fingers (26) in such a way that they can be rotated about the rotational axes (29) thereof. In order to grip the body (2, 2, 2″), the grip fingers (26) are displaced on a circular path. A central drive mechanism (22; 35) is respectively provided for the rotational movement of the holding elements (29, 31) of all of the grip fingers and for the rotational movement of all of the grip fingers (26).
