Yes. After removing the trigger bar assy from the lower, I took a wood screw and poked it into the no-pin side of the stock trigger in the same location as where you can see the head of the pin (it's a blind hole). Push until the pin pokes out enough to grab with pliers. The flat trigger comes with a new pin with splines which in theory should be much more resistant to coming out, since the plastic deforms around the splines.
