Hello, I have a norinco np-17 9mm, The mag does not want to release when the button is pushed. The only way the mag will come out is if you remove the clip that is holding the slide stop and then move the pin that goes through the slide out just a little then it will release the mag. I looked inside the gun and the piece that sticks through on the slide stop that goes into the internals of the gun hits the mag. i can assemble the gun and the mag will release but as soon as the gun is cocked it goes back to being jammed. someone please help and i will provide pics, if needed, thanks ahead for all the help
