[Borderlands 2] Why doesn't Roland's shield work in the cutscene following the death of Angel?

Title is slightly obscure so I can mark as spoiler (unless that's not how it works, I'm really bad at the whole "flair" thing) but when you kill Angel, Handsome Jack appears and shoots Roland in the back. However, wouldn't his shield stop the bullet? I don't quite recall but I'm fairly certain he has it active through the entire fight. How does it not stop the bullet?

There are definitely weapons in the Borderlands universe that bypass shields. At least, there's one sniper rifle. Wouldn't be too hard to imagine that Handsome Jack, with all the development power and capital of Hyperion, could have a pistol made that bypasses shields.

It could also be that Roland switched it off, thinking (incorrectly) that there was no more danger. Or it could have been broken in the fight. There's a few different possibilities.
