In my never ending quest for the ideal (for me) home defense handgun I am considering the DAO Beretta Centurion in 40 S&W. I currently own this gun in 9mm and love the Beretta DAO trigger, ultra smooth like a fine tuned revolver. My question is, has Beretta had any issues with the 40 caliber in terms of kabooms, excessive wear, etc.? I have shot this gun, it belongs to a friend that only put 50 rounds through it and I shot 25 of those rounds, and so it is in virtually new condition. I wouldn't mind having a duplicate copy of my 9mm but in the 40. Any experience or knowledge of troublesome problems would be greatly appreciated. I would prefer not to have internet rumors, if you know what I mean . Thanks
