So I'm curious where you got these "facts" CeeZer? Was not the Smith & Wesson Model 29 not the grandaddy of our .44 Magnums? Seems strange that the cylinder would be shorter than the design of the cartridge it was built forI've read that a Smith, fed a full time diet of thousands of exceedingly heavy loads can loosen up eventually but name a revolver that won't under those circumstances? And my 629's trigger is just fine, thank you.
The Redhawk cylinder is longer. My Hornady manual lists the max OAL for the .44 Mag as 1.610" and I load out to 1.700" with the Keith 245gr SWC in my Redhawk to hit the crimping groove correctly. I think the Super Blackhawk also has a shorter cylinder and must be loaded to the book OAL.
The S&W lockwork is more delicate than the Ruger and the timing will go off fairly quickly if shot double action a lot. The heavy cylinder and bullets overwhelm the lockwork and beat it up quickly. The Ruger is built like a tank and will not have that issue regardless of how you load it or shoot it.
That said, the Ruger will never have as sweet a trigger as the S&W. The Ruger is OK and can be improved with a spring kit and tuning, but the S&W is just in a different league.
