"In fact, since the spring is already at the bottom of the 13rd follower, how does it not over compress with 14rds"

Mark is spot on, it's not at full compression with 14. Very little is taken off the follower legs.

This is a sacrificial 13-round mag that I cut the side out of, so I could see what is going on with the spring and follower. It is loaded with 14 rounds in the photo.Click image for larger version
