I actually have one ss latch like that with the lock but i tried to match it onto my door and the hole was about 1/2 inch smaller in diameter so it didn't fit.
I'm assuming those M1 latches are maybe the correct diameter?
Unfortunately, I already ordered the stock latch but thanks for the info on the other ones, they seem to be the new standard on boats. (and the locking is nice)
