Chuck, I think you are right. It was getting late last night and I decided to call it a night. It did look as though I would need to take the safety switch off so the pin could be moved up and out. I just could not see how the safety thumb switch would come off. I need to get out my stronger glasses. It should help knowing a clip needs to come off first. I'll take another look when I get a chance and let you know how I do. I appreciate all you help, Dan
