rifling direction & recoil impulse

We all know that a handgun recoils upwards and back.

Does the direction of the rifling (RH, LH) imparts a twisting motion to a handgun's frame? And which way?

I am not experienced enough to sense anything but a straight up and back movement. You'd think that the force it takes for a bullet's jacket to engrave the rifling would impart some sort of side vector to the recoil impulse.

Asking the question because the answer has implications for our grip position.

Yes, the rifling twist does cause the gun to rotate in recoil. The gun will rotate in the direction opposite to the rifling twist when viewed from the breech end.

The effect will not be noticeable to the casual shooter, but serious target shooters will be aware of it.
