Weapons that don't reach very far? (5,4)
I believe the answer is:
'weapons' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for small arms that I've seen before include "Hand-held weapons" , "Rifle, pistol etc" , "Rifles etc" , "Portable weapons" , "e.g. Guns" .)
