Have always left mine on the M1P, same sort of bayonet prop fitting.
I use a larger fairly loose post office size rubber band around the body on my prop tips too, never an issue (4 years).
It depends a bit on your storage type, mine goes into a partition in a LowePro backpack, so snug but not tight, and a little flexible in the padded walls.
Been testing various props on mine, so removing and refitting quite a lot, I guess once you are used to removing after flight and storing separately, it's not that much of a hassle or too much time each flight.
