Some strategic tweaking of the follower spring might work. See if it comes up "straight" from the floorplate, or it it's tilted forward. If you;re holding the floorplate and the front of the follower is taking a dive, that's what I'd expect to see. Maybe a new follower spring is also a good idea because if it's an FN, that's what, mid Sixties? Spring might have tired out a little.
