Bond relies on his skills to get the job done, not gadgets
While there is an armourer and the Q Branch in the novels, they really don’t do much other than supply guns and other reasonable equipment. In fact, he comments in the books several times that he wishes his service had the capital to have an armoury like the Russians, or the equipment and cash of the CIA.
The whole ‘Q gives Bond a plethora of weapons, gadgets hidden inside things, and deus-ex-machina-type thingamajigs’ is just purely the invention of the studio and the writers.
It’s a shame, really.
