Just got a response from them for my request for the new followers, they should be here next week. They seem pretty responsive to this issue so that's a plus.
Range Update: Brought my gun out to the range, fired 150 rounds of ball and JHP with no issues. S&W did not give me new followers like other people received. The order sheet says they just replaced the mag retention spring. If any further issues arise ill just file down the followers.
Update
Just received the email today, my 45 is being shipped and I should have it back by next Tuesday. So that's about 5 weeks in their hands to fix the problem.
My own experience so far, I sent my 45 in on 4/17 and it was received 4/19. They started working on it (per the email they sent) on 4/24. haven't heard anything since then.
