Correct, and a double-action revolver (like the one shown) IS a semi-automatic weapon. One trigger pull gets you one shot with the next ready to go.

I never though of a double-action revolver as a 'semi-automatic." It doesn't automatically put the next round in battery when you fire it. I suppose you get one shot which each trigger pull, though.

Technically, revolvers are not classified as being semi-automatic.

A semi-automatic is a type of repeating single-chamber handgun that automatically cycles its action to insert the subsequent cartridge into the chamber.

A revolver uses multiple chambers and a single barrel.
