I do not know why the 75B's have a shorter trigger action than the older "pre-B' models. The older, longer trigger actions seemed lighter, and smoother, and just seemed a whole lot more user friendly than the newer guns. This makes me seek out the older pre-B guns, as I like the looks, too. The older ones have no slide "mini-rib", they DO have a rounded trigger guard and spur hammer...other than the more visible sights, the newer guns aren't as aesthetic as the old ones. Still the current crop are very well made, and serve most people well.
