No it wasn't a bad trigger bar, or mag spring and the frame wasn't out of spec. After removing the aftermarket extended slide release and replacing it with the original Glock slide release the weapon performed flawlessly again. Go figure! 93&pictureid=5497 The moral of my story is after having read and researched all the problems that could be causing the my own FTRTB, it wasn't a Glock problem, it was because of my own modifications to a perfect weapon. Your problem(s) might be as easy as this or as complexed as all the issues discussed in the thread referenced below which I labored over. http://www.glocktalk.com/forums/showthread.php?t=1062468 Here's hoping this might help someone else who is experiencing a similar issue.
