The trouble with short barreled Open guns is that they take more powder to make major, so they can get downright nasty.
You're right that a full sized gun with a 5.4" bull barrel and steel comp steers like a battleship, but if you use a Ti comp, a lightened slide and a fluted barrel (or better yet a bushing barrel/cone adapter), you can make a full sized gun swing like a shorty. During load development you'll appreciate an extra inch of barrel.
