Love mine. Heavy, absorbs the recoil, perfect match to my 1026. Getting expensive these days though. When one does come up, it seems to be in the $700-800 range. I think they only made a couple hundred of them.
I have a 4536 that I bought as a lark, and didn't realize what it was at first. Thought it was a .45 version, like my 4053 until I saw the decocker. Only read about them, heard rumors about them when S&W was making a different model every week. I would like to know more about them. Guess I have to get a letter....
