Mimic what the others have said with some more info. I own all of the popular .357/.44 mag revolvers and here is my 2 cents worth.
1. Ruger GP100 .357 and Redhawk .44 mag. Built extremely strong and will take a steady diet of any ammo withing industry standards of course. Any revolver will take a beating using full bore loads all the time. As far as I can remember the rugers are designed to take the cup limit and then another 50% on top of that for good measure.
I once witnessed a redhawk that a friend somehow double charged with Herco powder and was way over the cup limit. We were firing as normal at the range when a huge bang was heard and my friend jumping around the line in pain. The revolver had left his hand and hit him in the top of the head, just nicked him and blood was everywhere and he couldn't use his hand. Took him to the hospital for 15 stiches and his wrist was just sprained. We lived in Nevada and we sent the redhawk back to Ruger for a check up and it came back with no problems found, it survived like nothing happened.
Worst trigger of the three to work on and smooth, needs detailed work on the inerds to get a nice smooth action. Not bad but not as good as Colt of S&W.
2. Colt I have a Trooper and a Python. The trooper is a general duty type revolver with a smooth action and a good trigger, great little .357. The Python is what all other revolvers are compaired to, glass smooth action and exceptional trigger and top notch accuracy, nothing has to be done to the revolver. You pay alot more money for a Colt than really needs too.
3. S&W I have a model 28, 586 in .357 and 29 and 629 in .44 mag. These can take full house all day long but will wear eventually. Nothing has to be done to these revolvers as they come out of the box, smooth action and great trigger. Great accuracy from all 4 of them and once you find a load that works the best for each you are in the money. Very easy to take apart and repair, easy parts to find and the S&W forum is outstanding for info.
My personal ranking:
S&W 586 in .357 and 629 in .44 mag- great trigger/smooth action/great accuracy, average used price of about 400-550.00.
Ruger GP-100 in .357 and Redhawk in .44 mag Built extremely stong and heavier, with a bit of work it can be made to almost equal a S&W, used about the same as S&W.
Colt Trooper and then Python in .357 Trooper is a great smooth revolver with great trigger. Python is the best but at 750 and up for a used one it is not worth it.
