Picked up the replacement yesterday after work and I'm satisfied with it.
Fit and finish is the level that I expect and have typically experienced from Ruger.
The DA trigger pull measures just a skosh over 11lbs, is smooth and breaks clean.
The SA has a barely detectable hitch in it at just over 7lbs with a tiny bit of creep, but that should be pretty easy to remedy as should reducing the pull weights a little for both.
It is a shame that it took two tries with one debacle in between to get here, but Ruger did come through once again as you would expect them to.
Alright, here is a partial answer...
The Ruger Redhawk 5033 cylinder measures 1.781" in diameter and is 1.754" in length.
It has a 2.75" barrel and weighs 2.75 lbs. unloaded.
The Taurus 608SS4 cylinder measures 1.751" in diameter and is 1.686" in length.
It claims a 4" ported barrel, but the porting reduces the actual rifled portion of the barrel in contact with the bullet, to approximately 2.75".
Likewise it weighs 2.75 lbs. unloaded.
(Did I mention that I think porting on a .357 this heavy is a complete waste of time unless you're fond of trying to remove carbon from the sides of your front sight?)
Looks like the S&W weighs in at .4 oz. less with a 5" barrel.
Can't tell you the dimensions of the cylinder but maybe someone who owns one could measure the cylinder and post if there is still any interest.
