Jarek of Red Dragon Airsoft was doing video review of the WE Barry Burton Biohazard Custom M9 Gas Blowback pistol when he has barely inserted the third magazine to fire at full-auto when the slide blew-off during the blowback action. He was using propane at 85 degrees (F) outdoors (29.4 Celcius). There's nothing wrong with the magazine since it was feeding ok and no cracks in there but it is probably the slide disintegrating due to the vibrations caused at full auto.

Is this an isolated incident? If not, we would like to hear the experiences from other owners of the same model (the semi and full-auto one).
