1. A method of locking a barrel of a firearm with respect to a barrel slide, comprising: movably mounting a barrel slide to a housing of the firearm; movably mounting a barrel to the barrel slide; movably mounting a pair of locking bodies in a transverse groove of a head of the barrel; and securing a locking block to the housing, wherein movement of the head of the barrel with respect to the locking block in a longitudinal direction causes the barrel to be locked to the barrel slide, wherein the pair of locking bodies engage recesses on the barrel slide when the barrel is locked to the barrel slide, wherein the locking block has two first wedge surfaces which are symmetrical about a longitudinal center plane and the locking bodies are elongated cylinders, the circumferential surface of which has two parallel planar guide surfaces resting in the transverse groove, a second wedge surface which faces the other locking body and interacts with the first wedge surfaces of the locking block, and an engagement surface which faces away from the other locking body in each case and is intended for engaging in the respective recess of the barrel slide when the barrel is locked to the barrel slide.
