Ummmm... Yes. Any revolver can break, but the Ruger revolvers are stronger by design.
Stronger how? I do not see this specified by the cheerleaders. I just prefer to keep expectations realistic rather than parrot ideas.
People overemphasize this attribute when speaking of Ruger revolvers. I see a tendency on forums to expand the idea past a strong frame and cylinder. The small parts are important and break like any other gun. They are not indestructable at all and a double charge will burst a cylinder. That very thick cylinder wall on the Redhawk is a reloader's dream, but it can be pushed too far.
