I started this thread. In 2013, I bought a new production 4" stainless GP100, and a new production 4" 686 Plus. I wanted to compare them, and decide which I preferred. I never warmed up to the jerky 686 DA trigger. The Ruger had a longer, but predictable DA trigger. The accuracy was the same. The 686 had a better SA trigger. The 686 had softer edges, the GP100 had sharp edges, and a razors edge on the hammer spur. The 686 cost $200 more. I shot several thousand rounds from each, and I decided the 686 just didn't have the trigger pull that I liked. I traded it away, on a 6" stainless GP100.
Taking cost, ruggedness, and performance into consideration, I still feel the GP100 is the Greatest Double Action Revolver Ever Made.
I have enjoyed reading everyone's opinion, and I thank those who took the time to post. I'm glad there are some of you who agree with me.
