While I can't speak to the Sig 232 specifically, I am very pleased with my holster from K&D Leather
. I have one of their tuckable IWB Dakota Defenders, which is no longer offered, but it is absolutley terrific, and one of the most comfortable holsters I have owned.
I also like some of the simple ones from Bianchi and Galco, which are typically readily available without a wait time.
What style are you looking for? IWB, OWB, Shoulder? W/ or w/o added retention strap? Planned position for carry?
