Okay, I found the sister thread to this one, http://glocktalk.com/forums/showthread.php?t=1023139&highlight=RTB+meaning I was riveted to the thread in anticipation of finding out if Glock ever fixed the trigger bar groove problem. I read 58 pages! Just to find out, when I got to the end, the thread was CLOSED! I still do not know the stinking answer. Did the trigger bar grooving problem get fixed by Glock? I tried calling Glock today, several times, I could not get through to a customer service person, I was on hold for 30 minutes, and still no one answered.
