Regular publication (8)

I believe the answer is:

magazine

(Other definitions for magazine that I've seen before include "Weapons' store" , "Journal, periodical" , "Ammunition store; publication" , "Storehouse for explosives" , "Read it or keep munitions in it" .)

I've seen this clue in The Times.
