Corrected entry: Garth can apparently shapeshift clothes (or he doesn't wear clothes and the "clothing" we see is shapeshifted skin). But when Garth changes from Cory to Garth, a working phaser appears at his holster - where'd it come from? Or how'd he create it?
Corrected entry: Garth, shape-shifted as Spock, applies the Vulcan nerve pinch to Marta. Since Garth can only imitate the physical appearance of someone and not that person's life experience, Garth would have no knowledge of the Vulcan nerve pinch. The same could be said of when Garth shape shifts into Kirk - if Garth had Kirk's knowledge, he would have known the counter sign that Scotty used to challenge him for the beam up.
Correction: Garth, prior to being able to shape-shift and going insane, was a well respected Starfleet Captain and skilled tactician. In fact, he was required reading at the academy. Captain Garth would no doubt have extensive knowledge of Vulcans and the Vulcan nerve pinch, including learning how to do it.
Correction: The weapon was concealed while in the form of Cory.
