I decock just as ClickClickD'oh says. If you slip you end up with a mashed thumb at worst. Even so, you should always use care and keep the pistol pointed in a safe direction. Decockers can fail. I had a WWII P-38 that would reliably fire if you used the decockers.
Since I carry cocked and locked, this is less of an issue for me. I am still thinking about installing a single action only trigger.
