Grab a bag (4)

I believe the answer is:

grip

I believe this is a double definition.

'grab' is the first definition.
(I've seen this before)

'a bag' is the second definition.
(type of travelling bag)

(Other definitions for grip that I've seen before include "Ditch" , "interest - a lot!" , "Hold tight" , "mastery of problem" , "Purchase" .)

I've seen this clue in the Evening Standard.
