Clean it... well. Then put some oil inside the button of the mechanism and continuously press it.I have a new BP9cc with 500 rounds having been shot. The pistol is awesome and I am pleased with the gun. But, there is always a but, I am having a problem with ejecting the magazine. The button requires a great deal of pressure and the magazine does not drop clean. Does anyone have any information on this and can I fix it without going back to the factory?
