[1] Penal Code section 30515 lists a thumbhole stock separately from a conspicuously protruding pistol grip. [2] The rifle paragraph combines its listed characteristics with semiautomatic centerfire operation and absence of a fixed magazine; the shotgun paragraph uses a different combination of stock and grip characteristics.
