I just want to add that I went to see the film a third time today and I have to side with the thought that the film prop had the short grips throughout, I specifically looked for it in the snow scene. I am starting to think that there was indeed one hero prop version seen in the film with the shorter grips. I am pretty sure the snow scene is just a trick of the angle and there is a gap at the bottom as well.
That's what I saw as well.
