Was at the range yesterday shooting Glocks & 1911's and let a buddy shoot the G30. He fired several rounds and then stopped stating "I don't think a round fired". Pulled back the slide and found just the spent brass case still in the chamber. Dropped the mag with rounds still in it and checked the barrel to ensure the barrel was clear which it was. Scratching our heads at this point as to why the spent case did not eject & the slide did not recoil back when the round was fired. Pistol did not cycle. Put G30 back together and all was well, no further issues. Field stripped at home for quick wipe down & bore snake down the barrel. When reassembling I could not compress the recoil assembly to get it back into the pistol. Noticed the spring was starting to override the round plastic RSA end (end which sits in front of slide) and has made a gouge in the plastic. A slight twist of the spring and it could be compressed again. Twist in other direction and spring binds & will not compress. Anyone else ever see this???
