Sorry about that. I just responed to the inital post.Accuracy wise, the shorter barrel is as good, if not better than the linger barrel because of relative stiffness. This is more than offset by the reduced sight radius of the snub nose. This allows for small sighting errors to be magnified. The longer barrel allows more precise sighting and more practical accuracy.
That is not as big of a problem as you might think today. When we first started using the 125 gr 357 for our duty round we were issued Remington ammo. The muzzle flash was, to say the least, excessive! It was like lightning, even in daylight!Practically speaking, FBI studies repeatedly have shown that most defensive shootings take place at very short to point blank range, so that long-range accuracy (something you might well have trouble defending in court as self-defense) is not much of a consideration for CC.
Also, in a very short-barreled revolver flash and blast are magnified even with .38 Special. Personally I'd be concerned that in defending myself in the dark with a fire-breathing .357 I could be temorarily blinded by the first shot and less able to be aware of the state of the threat(s).
