Very comfortable raising weapons? (4)
I believe the answer is:
snug
'very comfortable' is the definition.
(I've seen this in another clue)
'raising weapons?' is the wordplay.
'raising' shows that the letters should be reversed in order.
'weapons?' becomes 'guns' (gun is a kind of weapon).
'guns' in reverse letter order is 'SNUG'.
(Other definitions for snug that I've seen before include "Comfy and cosy like bug in rug" , "Small bar in pub - warm and comfortable" , "Intimate" , "Bar parlour - comfortably placed" , "Cosy room" .)
