I purchased a Norinco Model 213 recently, it's chambered in 9mm. There are couple of things I'm having problems with, but the main one is the chambering of the first round. I've only put one magazine through it but once I got the first round chambered it seemed to chamber all the rest just fine. That first round or any round you try to manually chamber seems to stovepipe. It is seems to be jammed against the top of the chamber and the lips of the magazine or the feed ramp. My question is, will it hurt anything to alter the slop of the feedramp a little so it lines up with the rampped portion of the bottom of the chamber. It looks like this would allow the round to move farther out of the magazine at at shalower angle. Also is there a way to lighten the spring on the magazine release. The button isn't very big, doesn't stick out very far and is a real bear to push in enough to get it to release the magazine. I could sure use some ideas here guys. Thanks.
