It's not the bores themselves that should be of any concern, but the end-shake. We all know that every time we fire the gun the interaction between the cylinder and the yoke-rod "clash", which eventually causes end-shake. Any Smith revolver will suffer this condition under enough shooting. I just think the aluminum components can't stand-up to it like the SS, or carbon steel components can. I have an old aluminum cylinder and a yoke tube that has been stretched twice over it's lifetime and has an end-shake around .008 now even after the rod has been lengthened twice.
They are not likely to explode, but the surface areas in the yoke-tube to cylinder deserve much closer attention to routine cleaning and lubrication than a fully steel gun.
