Huben Huben GK1 magazine play

I've checked it and everything looks ok. After reassemble it was still the same. But there are no malfunctions or safety issues. It's been fired a lot. I must correct myself of how I described the play of the magazine. When it's locked it's not moving in CW direction only a little bit CCW.
Mine has been like that from day one. A few mm of play in the ccw direction.
