One in which the firearm fails to cycle, due to having a suppressor attached? And when you watch him clear the firearm, its very well practiced. It's not "fumbling". And it's always easier to clear, and fire again, then to keep trying to figure out why it didn't fire. Just rack it clear. Shit, I practice for that, with spent cartridges (To simulate a stovepipe), training rounds (For failure to fire), and other training issues for things that are good chances in the field.

I mean, I don't think this is a paid hit, either. A paid hit would have been a .22 fired to the temple, in all likelihood.
