That stands to reason if Ruger only losds were used but, if regular pressure loads are used there soulld be no problems. I can't remember anyone, here, saying they were as strong as a Ruger, nor as heavy, either? Yet, my 629-4 Mountain Gun will hold it own with any load I'm going to put through it. Smiths aren't the whimps that some poster imply they are, since the endurance package has been initiated. One has to remember that the model 29 has been around since 1956, and the basic design started around 1900?, and has undergone several engineering changes since then. Ruger Super Blackhawks no longer have nyloc screws either as advertised long ago.
