I have a Ruger Red Label 20 ga that I got new around 1981. It did not take a case of shells and when you hit the release latch the barrels would hit you in the shin. I have a Browning O/U 20 ga that has seen way more action that the Ruger ever has and it is still tight as a drum.
I had a 28 gauge Ruger that I traded for, major POS down the road it went.
