http://shop.cz-usa.com/ProductDetail/465423250012_Extended-Safety-Set-Shadow-2 Thanks all, need more help though. I don't want to appear to be doing too much hand wringing over this, but could someone please help me by looking at the Extended Safety purchase I'm about to make from CZ-USA at http://shop.cz-usa.com/ProductDetail/465423250012_Extended-Safety-Set-Shadow-2, take a look, and give me the "final" take...hopefully it will work. I can't see why not, being so many said their Shadow 2 safeties fit the TSO. Just take a look and let me know? I ask this because I wonder why the guy that answered the phone at CZUSA when I called, said he didn't think it would work, but after talking to all you guys the contrary appears to be true. I have only had this CZ TSO (my 1st CZ) for about 2 months so I'm not very experienced with them. Old 1911 guy. Thanks for your feed back guys.
