OWD: The only S x S gun that IMHO is more attractive with a ventilated rib is the Model 21 Winchester....or at least that I have seen. It seems the market agrees because the ones with vents cost more than matted. This may be due to rarity. I believe, and at one time I was a competition shooter, that vent ribs do dissipate heat. More importantly is to remove oils from barrel prior to high volume shooting. I have seen heat waves with a vent esP on a hot day. Obviously it evolved with competition shooting in mind. Some ribs on modern guns, e.g., adjustable ribs were developed with POI in mind. Buzz
Vent ribs on M21 are great--took the words right out of my mouth. Their value has nothing to do with rarity- it just looks "right" on the gun. The same cannot be said on the vast majority of other SxS's
with vents. As well the M21 is the only one that looks right with a beavertail too. Nothing looks more out of place than a Boss SxS with vent, pistol grip, amd beavertail......LOL. I think Niles has a 20 bore that scores a Trifecta in that regard
