Well, the Ruger aluminum gripframes were notoriously poorly fitted, with one ear or the other sticking up, etc., and they looked a bit different than the blued steel, as did the aluminum ejector rod housings. So, in the quest of "perfection", and having a "real" steel gun "like they used to make" some lke me have changed to the steel configuration.
In truth, the steel absolutely does not offer any improvement in durability...the Rugers are bull-strong as is. And lighter, too.
On the other hand, some of us just want personalized guns that suit our conception of what a "perfect" gun is at some point in time. My Ruger rear sights have almost all been changed to Bowens, for example, and most front sights have been changed to undercut patridges, because I see them better. The time and money I've spent on cosmetics and such? Well...we won't talk about that!
We've thoroughly hijacked Makilly's thread. Sorry.
