Can anyone answer this? What's the difference in the Ruger Redhawks thru the years? The reason I ask is, i tried a brand new Redhawk today. I shot an older one over 20 years ago, and I noticed a BIG difference in the two guns. The new Redhawk had a tight clean trigger pull, and it didn't rattle when you shook it. I asked the dealer when the change took place, and he said it just happened over night. Anyone narrow that down a bit?
