1. I carry a Springfield XDS in .45acp loaded with 230 grain Federal HST Tactical. I also usually carry at least one spare magazine.
2. I carry a Fobus IWB holster
3. I carry the XDS because it is reliable, small, and easily concealable. I carry it in the Fobus holster because it is comfortable, and because they make a holster designed specifically to fit the XDS.
