Not a 28ga, but had one in 12ga, and currently a 505 in 12ga.
Had to have the older 12ga stock cut down a tad for me, and it was a truly reliable waterfowl gun, wonderful shooting.
Still have the 505 in the safe, pristine, as I have gone to a 20ga these days trying to save my shoulder/ rotator cuff.
I know its not exactly what you're interested in. But as to the brand SKB, its a great shotgun.
