The Glock pistol, since it has a plastic frame, has all sorts of waves traveling through it, when it fires. IOW, it sort of behaves like Jello. Anything, rigid, attached to the rails will change the frames motion. Arc Angel calls it harmonic motion I think. If that's wrong, he will correct this. That's a good enough name for it, IMO. Actually, some steel rifle barrels will look like a sine wave, with high speed photography. That's why proper rifle bedding improves accuracy, sometime.
