I don't have one, but my understanding is that the C version starts at a half-cock position, so the pull is intermediate in both length and weight between the SA and DA modes of the more conventionally operated Berettas.
If by asking whether you can carry it in your waistband you are asking whether it is OK to carry it without a holster, I personally wouldn't. If you are asking about weight and size, the weight is moderate, and the most common complaint about the size of the PX4 models is the protruding safety levers. Without those, it is similar to others of the same capacity.
