While fooling around in my gun room/work shop, I see on the floor a little coil spring right in front of my gun safe. Now where the heck did that come from??? It is about an inch and half long and about a 3/16 o.d. with one end of the spring looks cut. Now I am wondering did this come out of one of my guns while I was cleaning them?? so I take everyone of the semi's apart look at the manual and drawings and everything seems to be in the right place. I wonder if my wonderful wife was in my shop doing something with what ever she does and it is part of her workmanship?? After taking them all apart and put bacl together they all dry fired, but it still has me wondering.
