A proper rib is smoked/cooked over real wood in Charles County, Maryland, by gentlemen of color, and finished with a vinegary sauce. Best location the junction of 224 and 225 at Mason Springs. Two slabs with mild sauce and one of hot sauce mixed together come out just about heaven.

As to shotguns, the rather high flat rib found on the early Remington Hammerless Doubles is my favorite.
