Stripping
| Check pistol is unloaded and remove magazine. Turn the locking lever by 180 degrees to the rear. | 
|
| Grab the pistol at the barrel. Receiver and barrel can now be drawn forward and be tilted for disassembly. | 
|
| Barrel/receiver unit must be held vertically with the muzzle pointing to the ground in order to prevent the bolt, recoil spring, firing pin, firing pin spring and firing pin guide from falling out. These parts are all placed in the receiver and bolt respectively without any fixation. Care must therefore be taken not to lose any parts. |
|
| Remove grips. Lubricate these two areas with a non-resinous oil (sewing machine, vaseline or spindle): a. Disconnector cam/trigger bar b. Turning-point of the trigger bar. |
