Ok so here is my problem. I took my 340pd apart to remove the internal lock. No problems there, I have done it on 4 other S&W's. The problem I am having is when I went to put it back together the "Hand" came off and I am having problems getting it back on. There is a small spring inside the trigger that came out and I am unsure of how it goes back in. If anybody can help me save a trip to the gunsmith I sure would appreciate it!
