No, there is ONE scene in "The Enemy Within" when Sulu removes the handle and puts on a new one . . . . unless my memory is faulty, which is possible!!! Funny, if you watch the scene, he actives the P2 emitter light while doing it! whoops!! lol It's one of the scenes when they are freezing down on the planet while warming the rocks. It's pretty quick and kind of dark but the white handle helps see it.
I will look for a screen cap
As I recall, this is the only time that we see the P1 get snapped into the P2, but the handle is still attached.
