I own three Gen4 Glocks. They all had smooth triggers: No grit, just a solid wall, a steady "whoosh" and a crisp break. The first time I cleaned one, I used Gunscrubber. BTW I'm NEW to Glocks. After lubing and reassembling, the "cleaned" pistol's trigger was hesitant. It seems to have several walls and breaks. I've tried different connectors, and even some polishing, but this particular pistol has never returned to its very satisfactory stock predictability. Anyone have any ideas? My other two are surprisingly good, and this one is surprisingly bad. Thanks.
