Dangerously off-topic now. The Model 520s were made in two frame sizes (much like the Model 12 and the Remington Model 31s). The Model 620s appear to have only one frame size (12-gauge!). Sadly, unlike the Model 12s and 31s, only the 20s were built on the smaller frame (all 16s were built on 12-frames, even in the 520-30s?).



Weight differences between the gauges were accordingly, significant. The 20s weigh-in at under 6 1/2 pounds.
