Hi,

I just installed a PGC Glock 17 metal slide and barrel as well as a Guarder steel trigger plate onto my Gen 3 TM G17. And now for some reason, the slide won't cycle back all the way when firing. Like when you shoot, the slide cycles just slightly shorter than needed to chamber a BB or lock the slide. So when I shoot, it shoots the first chambered BB but won't chamber the next ones. Despite all this, the slide feels very smooth riding on the frame.

Anyone know whats wrong?
(Oh right, I'm running on propane as well.)
