244,
I stand corrected, and i am sorry, i forgot all about "those" problems, and i have also had a very similar (if not the exact same problem) with my G20 a while back. I fixed the problem (as i refuse to wait for Glock) by "testing" the spring and follower by repeated "shoving" of the assembly into the mag until i figured out that if i twisted the spring in the opposite direction of the "hang-up" the problem went away and hasnt come back. The problem i had did not originate with Glock, but originated by my own doing when i took out the spring and stretched it out and twisted it unknowingly.
The problems you describe are really not a problem with the gun so much as a problem with the company itself called Glock. I am also a manufacturer, and if my employees (or myself) screw up on a process, all bets are off and the product is as good as worthless.
Your LEO agency is not the only one that has had the problems you describe. I thought you were refering to the San Bernardino Co. Sheriffs in California until i read further in this thread to find out otherwise.
I wish i could have responded to this thread earlier, appologized, and provided you with a little back-up... again i'm sorry... I also have a few "issues" with Glock "perfection", but, Glock happens to make the best 10mm out there, and until i find a better one, Glock is it. I can assure you though, if the Glock you have in your hand is "in proper Glock form" it will be reliable. Glock the company should be ashamed of themselves. I know i would be.
