TL;DR If you cancel a reload, you can't fire off the bullet in the chamber immediately. There's about a one-second delay.
Also, in the Firing Range, the bottle on top of the barrel by the laptop can't be shot unless you shoot at the base of it.

Sometimes it seems like more than 1 round is in the chamber when you do this too.
Edit: There also seems to be a bug when the gun kicks up from something being too close and it will not shoot.
