I always found that dry firing was a good way to check the pin. A #2 wooden pencil in the bbl. pointed at a safe open space, and fired. That pencil should really launch. Not something you would do a lot of, but I don't think it ever harmed one of my 1911's. Someone showed me that about a hundred years ago, it seems, can't remember who, but it really works.
I remember who showed me the pencil trick, it was my company commander in boot camp!
