The 39 year old practised using the firearm for months before she was due on set, but admits she was still wary about firing the weapon when the time came to film her scenes.
Bingbing tells Britain's Ok! magazine, "Even after training and a couple of months of shooting my gun, I was a bit nervous and blinked every time I had to pull the trigger!
"It's not only because the gun is so powerful and pushing back at me, but the sound is deafening! But even the most experienced action stars in the industry continue to be nervous when they pull the trigger. I had nothing to worry about!"
