I don't know if you are being purposefully obtuse or just don't own any handguns. He is pointing out the fact that many guns, such as the aforementioned Glock (sights) and also the S&W M&Ps, have required some kind of upgrade to make them more usable.
Where are you getting $600 from? I have seen them for much less most places.

I enjoy my P226 Mk25 and has never had a problem. The 320 drop safety problem and the issues with the 365 haven't been forgotten on many people . I'd rather wait awhile and make sure everything is sorted out. Their P-series guns are great, but they've had some problems with their last 2 polymer guns.
