ISSF has two stages in the Centerfire Pistol match.
Slow fire, 5 shots, 5 minutes, six times.
Rapid fire (They used to call it The Duel.) Targets face you (or you get a green light) for 3 seconds, face away (or a red light) for 7 seconds, back for 3 seconds, etc for 5 shots six times.
Can you cock a revolver and get your attention back on the target in seven seconds? It is certainly possible, there were a fair number of revolvers shot before the .32 wadcutter autos got refined, but it is going to take some effort that the automatic takes care of for you.
