GREAT guns. I just took one home the other day. When I got it home, I sat down with a cup of coffee and started to work on it. A thorough cleaning and some cannibalization of some other 3rd Gen parts netted this.
Today, she was sent off to the factory for the 'Decock-Only' modification and the loaded chamber witness hole.
Unlike the 910/909/908, she has NO plastic parts whatsoever and uses the single lug lock-up design. They are in effect a newer model 459.
They have much to recommend them.
