I have one, I like it quite a bit, and carry it often - it is a good shooter.
I got it to use as a deep concealment piece. It works out well because I also have a P-10 S and C that I carry depending on the occasion, so I don't have to train across platforms.
What I like about it most is how well it conceals - it is really easy to hide no matter how you dress.
What I don't like is the lack of aftermarket support - but honestly...for what it is, you don't really need to change anything about it.
There is little to no aftermarket accessories for them unfortunately. Even holsters are pretty hard to find, Vedder is the only vendor I know who still offers one.
CZ Custom has +3 Magazine extensions for them - that will get you up to 10 rounds.
I don't know of anyone who is offering aftermarket sights, but CZ custom will cut the slide to accept a holosun red dot.
FWIW - I would buy it again for a deep concealment option.
But...the P10S is also extremely easy to conceal, holds 12 rounds, can be had optics ready, can run 15 round P10 Magazines, has a standard P10 Trigger, and a heck of a lot more aftermarket support.
If I could only have 1 - I would go for the P10S hands down.
