Just got ahold of Dan at Glock and he informed me that if I send my magazines in they'll update them to the current spec free of charge, and that if I talk with my Glock armorer buddy at the PD they'll send a free updated connector to him.
Call took all of 3 minutes and I wasn't put on hold a single time. Two real people. Major points to Glock customer service. Talking to a highway patrol trooper a year back and he said that the reason the agency went from Glock to M&P and then back to Glock was that they missed that service. I see what they mean.
