Two Piper not only had a 12 gauge frame on his 20 gauge 870, it didn't weigh anyone's 6 1/4 pounds. I still have my standard weight 20 Sunlight around here somewhere. I ran 100 with it at the Maryland State NSSA shoot one year and lost the shootoff in the first pair because I switched to my K32. Model 42s don't have to weigh a lot to be competitive. My prewar solid rib 42 with steel Cutts has run 100 straight and also has run 244X250, both on the same day. I won't do that again.
