The P229 is a great platform, but when compared to some of its competition, can be a bit bulky. I have a Legion P229 that I plan on using as my CCW, but it is certainly chunkier than my Walther P99, Glock 19 or certainly my Wilson Combat 1911. It is doable, but if you're planning to appendix carry, I'd recommend going for a variant that lacks the beaver tail, so no Elite, Enhanced Elite, or possibly Legion, though the profile of the latter is quite a bit reduced from the others, it's still definitely present and pokey when seated.
