try watching it again, it just worked for me just now. I talk for about a minute before anything happens in the video.
ok i just watched the video. yeah that's the same malfunction that's plauged a bunch of g30/29 SF models.
a few of the threads on other forums i've read said glock told them to keep shooting to "break it in", and sometimes that's even worked. howoever, with the cost of .45acp ammo, that's an unnacceptable answer for an issue glock should have resolved years ago.
i see you had to handle it pretty hard a couple time just to get the round out of the chamber torwards the end. somethings definitely contacting something it shouldn't be.
since glock has never admitted (or even fixed) the issue, no one's sure if it's actually the trigger bar rubbing the slide that's causing the issue; or if it's the same issue causing both the trigger bar rubbing
and the failure to return to battery probs.
there's been talk of out of spec frame rails. some think their rear rails are lower than the fron ones on these guns. mine appears to be like this at first glance on my g29, but it's not. the polymer frame just comes up higher at the rear of the frame so it's closer to the rear rails. they're level with the front rails.
so if you read about "the nickel test" (putting a nickel under each reail to judge the distance), this is nothing more than an idiotic rumor started on GT.
