POW grip

[Dean Romig]

A "ball grip" differs from a "pistol grip" in that it has a pronounced swelling at the knob of the grip where a pistol grip (not to be confused with a "capped pistol grip") does not have that swell. A true Prince of Wales grip generally has neither and has a much more gradual (almost non-existent) radius to the tang area.

[Bill Murphy]

A true Prince of Wales grip is not a ball grip, but a gradual pistol grip, usually with cap at less of an angle from the horizontal than a normal capped grip. Look at the "stock grip styles" on the Hallowell site. That is a classic POW grip, probably pictured on a Woodward shotgun. Woodward used the classic POW style stock on many of their pistol grip guns.
