I have both. First I got my P10c, used it exclusively in an last years IDPA season. Also, last year I obtained a P10S.
I like both guns, both are non optic ready.
I find the S not much smaller than the C- almost to the point of wondering why, being roughly a thumbnail shorter in height and length.
So in practical terms which do you prefer and why?
As for me, it’s the C. As it’s not much larger than the S, I can carry it just as well, it contains 3 more rounds, and I don’t have to adjust my grip to ensure the mag drops free.
I do like and carry my S, but between the 2, the C is the one I’d keep.
