I've been carrying the SD9 in a Comp-Tac CTAC IWB kydex holster. On the off side, the spare magazine is in the Comp-Tac single mag pouch. My belt is the Spec-Ops Brand "Better BDU" belt. Worn under a shirt, it's never seen.

The CTAC is comfortable and I've worn it in varying environments.

I like the pistol and this setup.
