Notice that most all the S&W PPC revolvers are sporting non-factory barrels. Custom heavy barrel with a 1 in 12 or 1 in 14 twist.

The reason is that the factory Model 14 barrel is not very accurate out to fifty yards. They were 1 in 18 3/4 and would cause the bullet to yaw at 50 yards. Some worse than others. I have seen some that would strike the B-27 target almost sideways.
