did you take apart the "multifunction element"? couple of springs in there that you have to watch out for, or try to see where they flew off to. look for shiny places inside the gun where wear is happening, look for burrs, look for dirt and schmutz. this is rumor so far, but Steyr at some point did some modifications to the pistol design and got rid of some problems and complaints. I don't know the time frame on that. don't know what to do with and older gun. I don't want to promote bad behavior, but dumping the gun for "the right price" at a gun show is always an option. have you talked to Steyr about sending the gun in to them for a checkup?
