My GP 100 6" is a very, very accurate pistol with 125g Sierra and Hornady XTP's with IMR 4227 and H110. I replaced the front sight with a beade sight and a V Notch rear sight. This combo makes for some very accurate pistol shooting at some distance. I doubt you will ever live long enough to shoot a GP 100 loose from hot loads.
Replace the spring in the grip of the GP 100 and you have one more sweet trigger.
My 686 6" is a really nice gun, but it is not as accurate as my GP100, but the trigger is smoother on double action. The 686 is not as robust as the GP100 in terms of strength. You can do nothing on the 686 Sights.
I have killed 6 coyotes and two Javelina with the GP 100 with the 125's.
If you ever get the chance to get a Ruger Red Hawk in 357, Buy it!
