Here's an interesting comparison:
Your Raging Bull has two cylinder lockup points, one at the crane and one behind the cylinder at the normal location for an S&W or similar. Controlled by two different switches.
Now open the cylinder of your Redhawk and look at the crane and the frame where it goes into, and hit the cylinder release button a couple times.
Spot it yet?
Your Ruger also has double lockup, but by way of a linkage running right through the cylinder, the ONE lockup release button controls both lockup points.
What Taurus needed two switches to accomplish, the Ruger pulls off with one. And they do it on the SP101, GP100, Redhawk and SuperRedHawk.
(I'm not certain about the older Service/Security series DA wheelguns...probably though, as the Redhawk is basically the old Service/Security gun "supersized".)

I also believe Ruger is simply making better guns lately. QC at Ruger has at times varied; somebody has decided to get this literally under control. They're still not at Freedom Arm's level but if they keep this up a while, I might be inclined to buy one new through one of the distributor programs sight-unseen. Right now I would only do that for an FA or Korth, and am still recommending personal pre-purchase inspection of any new Ruger, S&W, Taurus or lower grade.
When I bought my New Vaquero, I was only able to find blue specimens in the caliber I wanted (357). I settled for a blue gun I could hand-inspect versus special-order a stainless I couldn't.
That's still my recommendation for anybody. You can live with a gun that's a bit off from your first choice better than you can live with a gun that's mechanically "a bit off".
