That's a good catch. Here's some more information on the CZ P-10 SC.
https://www.czub.cz/en/produkty/pistole/semi-compact/cz-p-10-sc.htmlIt seems that CZ did exactly the opposite of what Glock did when they introduced the G45. Glock took the full size G17 frame and put the shorter G19 slide on it, and for doing that they received a lot of criticism from Glock lovers who wanted a short G19 frame with the longer G17 slide, stating that they wanted the shorter frame so that it wouldn't be as noticeable when carried concealed.
Evidently CZ was listening because the new P-10 SC does exactly that by using the P-10 Compact frame and pairing it with the P-10 Standard slide.
Since then, it seems that people have been warming up to the G45. It is the size that that is popular with law enforcement because it has a full size grip for comfort and control when shooting, and it holds 17 rounds, but it has the slightly shorter barrel so that when they are sitting in their patrol car, the barrel doesn't dig into the seat.
It seems that there are valid reasons for both the long side/short grip version and also the short slide/long grip version. I wonder if CZ will come out with yet another version of the CZ P-10 to cover all bases.
