I don't like vent ribs stepped up and high. The 21 and Parker are a little high, but not so much to be objectionable. I think 26" 12 gauge vent ribs look out of proportion, but I shoot my 26" vent rib PHE Parker very well. However, it looks better with the 30" barrels. My 32" vent rib Model 21s look like shotguns should look.
