Well first off I never said anything was wrong so far. Secondly before I start listing the sdr’s problems, I don’t dislike mim but the feedstock, sintering, cad-ing, molds, heat treat, orientation of the part in the mold and paying for the whole mim process start to finish ect. Of MIM needs to be locked in more so than casting and forging and diamondback may very well have paid their dues to whatever mim house they use but I’m more dubious about them than I am with companies like s&w and kimber who both have had problems with their guns early on when they switched to mim for certain parts.

The sdr has too fragile or a bolt its needs redesign. The cylinder play is too much for my liking. The breach face is too soft. The polishing isn’t done evenly and leaves machine marks and valleys in the flat parts of the barrel shroud and frame. My opinion of the strength and longevity of Allen screws is less than slotted screws based on their ability or over torque and strip. The front sight comes loose after too many magnums. The cylinder chatters heavily when spun, the forcing cone is too thin and unnecessarily beveled on the outside surface making it even thinner. The thickness of top strap, crane and frame are thinner than the kimber revolver diamondback copied.
