The first time I saw these stocks was at a PPC match in the mid 1970s. They were very popular with a number of shooters there. I thought about getting a pair but I was shooting a Ruger Secutrity-Six bull gun and I don't think they were making them for Rugers then. The picture posted earlier of a pair on a Ruger made me envious, except the bull gun is long gone. (smile)
