The thing is I have bought a Hammerli X Essse Sport and after the last shot, the slide does not stop after ejecting the brass and consequently the chamber is closed instead of open
The model is this one

I have checked, rechecked, cleaned, lubricated, tried with magazines from other pistol, etc, no way... If you do it manually, this is, you put an empty magazine and rack the slide, it keeps in rear position and the slide release button works perfectly.
Which is strange is that the first couple of shots after having cleaned and lubricated the gun, it works, but that's all, the following shots it does not work.
Any idea ¿?
Thanks in advance!
