1911/Hi-Capa AFAIK are single action only. The most basic is just in single action the trigger works only if the hammer is cocked. The double action can cock the hammer and shoot in one pull. Most guns now are SA/DA(M9, Sig, USP...etc), so the first shot can be shot from double, then hence forth the gun works and SA, until the hammer is decocked with a decocker. 1911 is typically SA only. Some of defensive pistol for enhanced safety, works only in Double Action Only.

Glock, M&P...etc are striker fire, and for all intents and purpose operates similar to single action, though nomenclature differ. Glock calls theirs "Safe Action". The pulling the slide back from the first inserted mag put the striker in half-cock position. The trigger pull completes the full cock and firing, and the striker returns to the half cock for the next shot, its not a true SA or DA...Airsoft version of Glock AFAIK does not really work like that.
