Leathal diamonds, not to bash Smith&Wesson but I have on good authority [my dad] who has been selling guns for 35 years the Ruger hand guns are alot stronger than the Smith&Wesson guns like I said to each his own but the Ruger handguns will take anything you feed them. I shoot Buffalo Bore ammo in my Ruger's which are loaded max and then some and I have had no problems. chad
