Sorry.

Double action ... when you pull the trigger it cocks the hammer, pushes a round into the chamber, and fires the gun (by releasing the hammer).

Single action ... just fires the gun (hammer is already cocked and round is already in the chamber).

The trigger pull to simply release the hammer is short and light. The trigger pull to cock the hammer, move the round and release the hammer is long and heavy.
