Does anybody here know if the rear sight cut on the Sigma Series is a Novak, etc. or is it a proprietary dovetail/relief cut unique to this line? Mostly looking for input from gunsmiths or experience in substituting other sights on this gun. What I am not interested in is why you think as prospective purchaser should select another gun, and if the thread goes there I'd like the mods to lock it immediately.

Thanks in advance. I'll email S&W on this subject & post whatever info I get here.
