Sandy Chisholm, NAA owner for 20+ years, released photos of prototype swing out cylinder based on 22magnum frame. This will be shown at NRA banquet 4/15/12. Date to be released for sale, unknown.
This is an excellent idea, long overdue in the making........but, it looks like it is made for a Southpaw since it swings out on the WRONG SIDE!
They also need to design a speedloader, (aluminum, NOT plastic) for it.
