Funny because I have two Canadian Edition Shadows, and both have fiber optic rear sights, from the factory. Also came with flush safeties, as per the Shadowmate designation they now carry. There is a thread on here somewhere showing all that. So, no, the only difference isn't the narrower front sight, it's also the hand picked frames, the different finish, the more precisely hand fitted barrels, slides and frames, the competition hammer and sear being better fitted, the aluminum grips (that are neither thick nor thin, but in between, so a medium). On the newer guns it's also a chromed barrel. Cost of the original ones were $1500 for the high grade, now it's $1800.
Did I mention I have two of them? And that I sat in on a design meeting in Czech with Boris and Petr and the head of pistol production at the factory in 2011 and 2012, talking about things we IPSC shooters wanted out of the pistols. They haven't done the checkering a bunch of us have asked for though.
