The Blackhawk .45 Colt with 5.5-inch barrel is an intermediate configuration between the cavalry-length 4.62-inch and the longer hunting versions. The 5.5-inch barrel is a traditional revolver length that provides good balance and modest velocity improvement over the shorter barrel. This configuration is popular in cowboy action shooting where the 5.5-inch barrel suits period-correct presentations.
