Well a couple of weeks ago I posted that my slide failed to lock back after the last round fired. I recieved a new mag that I ordered, and with the new mag I have had no locking failures. The pictured mag is the old one that I have been having problems with. As you can see the follower leaves the mag completely passing the slide lock. This time it was very difficult to remove the mag. If any one else has locking problems, maybe this could be a reason why. I am going to send the faulty mag in on Monday for replacement.
