Yes I did tear down the P11 and the spring was broken,it was actually sticking out between the slide and the frame when it broke. I haven't taken the Guardian apart yet when it happened I was so frustrated I just put it away. I will though. I have dry fired my Guardian a lot , could this be part of the problem? I know some people say never dry fire some say they have done it a lot and nothing has happened to them. I haven't dry fired the P11 at all and it only had 150 rounds thru it when it broke.
Sometimes I catch myself not allowing the trigger to return all the way to the front before I pull again could this be putting the spring on a bind and causing undo strain?
