1. A handgun (90) with a silencer (10) and with a fixing device for fixing the silencer (10) to a handle (92) of the handgun (90), wherein the fixing device comprises:
a fixation rail (30) for fixing the fixing device to a mounting rail (94) of the handgun, wherein the fixation rail (30) has two upper side walls (31), the two side walls respectively comprise inner longitudinal guides (32), which are configured as guide grooves, wherein the guide grooves correspond to the mounting rail (94),
wherein the mounting rail (94) is provided at a horizontal section of the handle (92) directly below a barrel (91) and forward of a trigger guard (97) of the handgun (90),
the fixation rail (30) is arranged at a rear end wall of a silencer housing (11) of the silencer (10), wherein the rear end wall of the silencer housing (11) is facing the barrel (91) of the handgun (90) when fixing the silencer (10) to the handgun (90),
wherein the fixation rail (30) and the silencer (10) is formed in one piece,
wherein a support surface (36) is formed at the rear end (33) of the fixation rail (30), which at least in sections rests on the front end (97a) of the trigger guard (97) of the handgun (90), if the fixing device is fixed to the handgun,
wherein a surface of the support surface (36) facing the trigger guard (97) has a convex curvature,
wherein the front end (97a) of the trigger guard (97) is formed as end wall-sided counter support surface, which at least in sections corresponds to the convex support surface (36),
wherein the support surface (36) of the fixation rail (30) rests in a substantially positive-locking manner on the end wall-sided counter support surface (97a), if the fixing device is fixed to the handgun, such that the silencer (10) is reliably prevented from oscillating in a vertical direction (P2) after a shot has been fired from the handgun (90), and
wherein the support surface (36) at the rear end (33) of the fixation rail (30) has an axial recess, with which an axial protrusion or pin (97b) arranged at the front end (97a) of the trigger guard (97) engages in a positive-locking manner, if the fixing device is fixed to the handgun.
