Nope. Semi-automatic and automatic refer to the feeding mechanism between rounds discharged, not the trigger action. While you can accomplish the same firing speed, more or less with a double action, rotating individual chambers is different from a spring using the energy of the last shot when the slide moves to make room for the next spring fed round round. Revolvers are classified differently from "semi automatic" handguns (and shotguns/rifles/carbines etc.)
