[M12 Stubby Issues?]

Hi everyone. I bought recently an M12 Stubby 1/2". I noticed since new a little of play in the half inch square pin, that is getting worse despite the rare and light usage I made of the tool till now. To explain better, if I push with my hand the pin inwards, it moves a little. And you notice that while trying to fit a socket for example (I use a little of grease to facilitate the process). I'm not an expert in impact wrenches, I'm new to this world. Could someone be so kind to tell me if I have an issue? Do you think it's better to bring it to an authorized dealer for warranty? Thank you very much for help
