How tight do you try to get your mag to fit up against your trigger guard front?
 I had it at first where i really had to push the mag in real hard to get the release to snap in.  I ground a little off and now it has a little bit of wiggle (up and down, not forward and back)  But before i ground the front of the trigger guard a bit the mag would cram up to the trigger guard plate and give no up not allow the mag to go in far enough to have any play at all.  So what is a factory AK suposed to be like??

You want it to be tight but not so tight it is difficult to get in.

You know . . . . . . kind of like a woman.
