You forgot the failed Hong Kong Police adoption of the P250 which resulted in the HKPD re-adopting new S&W model 10 revolvers.
Not sure if this answers the question but it’s important to remember there were two generation of the P250 and the first generation was a giant turd. By the time SIG fixed the P250 into the Gen 2 which some of PF looks on with so much nostalgia the damage was already done.
There wasn’t a direct safety issue as with the P320 drop gate issues so there was no recall or upgrade program. However SIG never formally acknowledged the generations, it was just a rolling change.
