Description

TECHNICAL FIELD The invention relates to a slide assembly for a firearm, as well as an indicator for use in the slide assembly, and a firearm comprising the slide assembly, and a method for assembling the slide assembly. BACKGROUND DE 164853 C discloses an indicator for a firearm for indicating whether a cartridge may be loaded in a cartridge chamber. The indicator is a rocker arm that is pivotably mounted in the slide by means of a pin. The firearm known from DE 164853 C has the disadvantage that it is only with difficulty that the indicator can be fitted in the slide. Other similar indicators are known from EP 1586846 B1, DE 370907 C, U.S. Ser. No. 11/519,692 B2, U.S. Pat. No. 8,109,023 B2, U.S. Pat. No. 8,245,426 B2, U.S. Pat. No. 891,438 A and also from certain versions of the Springfield model XD pistol. These so called chamber status indicators or loaded chamber indicators are used in some firearms in order to comply with the laws of certain U.S. states. Nevertheless, a user should not rely solely on a loaded chamber indicator to determine the loaded status of a firearm equipped with such an indicator. Safe firearm handling practices and the instructions and safety warnings provided by the firearm's manufacturer must always be followed to minimize the risk of a negligent discharge, serious injury or death. OVERVIEW The object of the present invention was to overcome the disadvantages of the prior art and to provide a slide assembly, as well as a firearm equipped with the slide assembly, which improves the reception of the indicator. This object is achieved by a device and a method according to the claims. According to the invention, a slide assembly for a firearm is formed. The slide assembly comprises: a slide;a barrel with a cartridge chamber;an indicator for indicating whether a cartridge may be loaded in the cartridge chamber, wherein the indicator has a first lever arm and a second lever arm, wherein the first lever arm extends in a longitudinal direction into the cartridge chamber, wherein the first lever arm has a cartridge butting area for butting against a cartridge that may be received in the cartridge chamber and wherein the second lever arm is turned away from the cartridge chamber, wherein a pivot bearing for pivotably receiving the indicator in the slide is formed between the first lever arm and the second lever arm, wherein a barrel receptacle for receiving the barrel is formed in the slide and wherein an indicator receptacle for receiving the indicator is formed in the slide. The pivot bearing has a first pin on a first side and a second pin on a second side with respect to a transverse direction. The indicator receptacle has a first pin receptacle and a second pin receptacle, wherein the first pin is received in the slide in the first pin receptacle and the second pin is received in the slide in the second pin receptacle. The slide assembly according to the invention has the advantage that a stable reception of the indicator in the slide can be achieved by the pivot bearing according to the invention. In addition, by means of the measures according to the invention it can be achieved that the indicator can be easily inserted into the slide and can be easily removed again from the slide. In particular, by means of the measures according to the invention it can be achieved that the indicator can be inserted into the slide and easily removed again from the slide without the use of a tool. Overall, the user-friendliness can be increased by the measures according to the invention. The pins arranged on the indicator can also be of a robust design, so that the lifetime of the indicator can be increased. In addition, the indicator according to the invention allows the number of individual parts to be reduced. Furthermore, the indicator according to the invention can be easily manufactured. In particular, it may be provided that the indicator is designed as a rocker arm. It may also be provided that the indicator should remain in a rest position when no cartridge is loaded in the cartridge chamber and that the indicator should remain in an indicating position when a cartridge is loaded in the cartridge chamber. In particular, it may be provided that the indicator can be tilted between the rest position and the indicating position. It may also be provided that the indicator should move into the indicating position by a cartridge that is loaded into the cartridge chamber. The cartridge in the cartridge chamber should press against the cartridge butting area so as to move the indicator into the indicating position. It may also be provided that in the indicating position an indicating area of the indicator should protrude from a slide surface of the slide. It may also be provided that an indicating coding is formed on the indicating area. The indicating coding may be for example a colour marking or a colour dot, preferably provided in a depression to potentially reduce abrasion. The colour mark
