What's the purpose of the oval foam cutout?

[Zumkopf]

I just got my brand new blue plastic "medium" case from Smith & Wesson (something about keeping a pistol in a cardboard box didn't seem quite right). There is an oval cutout in the upper foam on the left side. Can anyone enlighten me as to what is the purpose of the cutout? Thanks, Z

I think thats where the paperwork goes.

Yes, that's where the paperwork (manual, warranty, etc.) goes.

Ah, now I see.

It was the oval part that threw me off. Thanks, gentlemen. Z
