Just slightly puzzled over this one:-
26 Down - "Stock worker has endless complaint"
The answer is obviously "HANDGRIP", which is HAND +
GRIP(E), but how does the answer relate to "stock"?
the part of a rifle or other firearm to which the barrel and firing mechanism are attached, held against one's shoulder when firing the gun.
synonyms: handle, butt, haft, grip, shaft, shank, helve
"the stock of a weapon"
