Notice how well the muzzle flip is controlled in a properly designed and
handled revolver. Mine has even less muzzle flip, it's heavier with a 6"
barrel.



First, a disclaimer. I don't know what I am talking about. I am not
an expert in shooting or handguns and don't shoot that often.

That said, I could make an argument that "muzzle flip" is naturally
greater with a six inch barrel than a 3 inch barrel, purely from a
mechanical advantage point of view. This assumes the rounds are of the
same caliber and load, of course.

Picture the handgun as a lever with your hand or wrist as the fulcrum.
The force of the bullet exiting the end of a longer barrel is going to
impart more off center force on your wrist than from a shorter barrel.

I am sure the weight of the handgun plays a role but I suspect the
difference of 2 or 3 inches on the barrel length is minor. Energy (or
in this case force) is mass times velocity squared.
