It probably is a better gun, but the Cowboy shooters found the SKB's and prices, that I have seen, are in excess of $2000 used and that's before the gunsmithing work to make them race guns.
Interesting. I sold one a couple of years ago for $1000 ( the more desirable 27+" 20 gauge), and have another 25+" 20 gauge left to go. Good to know it's now a $2k gun, because I've never heard of $2000 SKBs nor of Cowboys cutting them down. They are good guns and 12s used to be abundant enough to be a nuisance when shopping for a 20. I haven't followed them in years, however.
Most cowboy shooters aren't interested in 20 gauge shotguns regardless of make. Fewer ammo choices for those that don't reload and a 20 gauge on 20 gauge sized frame with short barrels has a reputation for kicking badly.
They bought up the 12 g SKBs, had gunsmiths shorten the barrels, polish the chambers and if they had inertial triggers, the gun was modified to make them mechanical triggers.
And a casual search shows SKB 12 g SxS running between $1500-$2000 on a couple of the gun auction sites. I think I got the $2000+ amount from cowboy shooters selling them on the SASS Wire
