Vicky fires first seven, then another 13 rounds from her Beretta 92 pistol without reloading. While there are 20-round magazines, and you can never really see the magazine, the next time she shoots - which is in a different scene where she could have reloaded off camera - she runs out after only four rounds. From her cupping grip on the gun, it is clear that she has not been using a 30-round or larger magazine either since those stick out of the grip too far.
