Several handgun cartridges are subsonic - 45 ACP, 38 SPL, .380 Auto (not the +P versions of these which have more zing to them). A 40 cal with a heavier 180 gr bullet would be subsonic in most cases, though there are some really stout brands of ammo out there.
Sorry - rackin’ the ammo slide.

Also 9mm in 147gr or heavier is subsonic, as is 45 ACP in 230gr.
