Well, operation 'keep the thing distracted so it doesn't focus for too long on one person' seems to be working, more or less, and the monster also seems to be injured.

Unfortunately, Nick's also out of ammo, and wishing he had a second weapon. He's always relied on hand to hand combat first, and his gun as back up, but now he's starting to wonder if maybe he shouldn't be exploring alternatives. Of course, that doesn't exactly help him at the moment, but - with the monster focusing his attention on Richard and the other gunman, Nick takes a moment to reload his gun.

And then goes back to carefully taking aim at the monster, this time shooting for the same arm that the other gunman'd shot at.
