There are some almost personal attacks going on here - let's not do that, shall we?
I will probably get one too, and I do like the concept of a BUG, which right now my P-10S works perfectly for. The internal slide stop is probably in part because the P-10 slide stop is factory stiffer than a life sentence and over the top is the best way to release it anyway.
I would love to try this - shot the brand new Glock single stack two weeks ago and was seriously unimpressed.
ANother thing to consider is a 7+1 gun will sell in states/locales that restrict magazine capacity, especially those that say "firearm that can accept a magazine greater than 10 rounds), which every other P-10 can, so this might be the slide for CZ into some restricted markets and get people to experience CZ goodness as well.
