Sounds highly plausible to me. Thats what Michael Corleoni used when he snuffed out the two trouble makers in the restaurant. Very easy to muffle sound..or so I've heard. Robert Dinero used one in his S. Americkan hit man movie. He had the micro mini 5 shot revolver. He push them in the bathroom stall and one shot in the heart and they die instantly without any noise. I think they took some artistic license with some of that story line. I have one..they make a purty good bit of noise. Jump right of your hand if you aint careful. Better to shoot with two hands. Left to hold the gun and the right to pull the trigger.
