40/2.8 tight on the mount

I just got a new 40/2.8 pancake (congratulations, thank you). When mounting it turns the first half of the arc just like every other lens, then it suddenly gets quite tight, requiring a deliberate grip and effort to complete the rotation.

Anyone else have this, with any lens?

I'm going to check the mount carefully for burs, etc., and if it's not obvious and easy to fix I'm tempted to exchange it for the sake of my peace of mind. Reasonable?
