I really don't want to make this about me, her, or our friendship, but no, it's not Sharon Stone. That would be great, though.
My actress friend (Charlize Theron) played Aileen Wuornos in the movie Monster, where despite a an initial budget of $1.5 million (later investments bumped it up to about $5 million) guns and gun safety played a prominent role in the filming. Wuornos killed 7 men by shooting them at point blank range. Everyone on set was anal about the weapons safety protocols, and ever day that involved a gun started with a full safety meeting with anyone who would be on set that day, including cast, crew and visitors. I was on set several times, 15 days total, but not in a row, mainly for moral support for Chaz because she was an emotional wreck during the times of the most difficult scenes.
Funny story... There's one scene near the end of the movie where Aileen shoots and kills a man on a bridge, and she is distraught to the point where she throws the gun off the bridge into the river. Under the bridge in two rowboats on the water were crews with large fishing nets on 10 foot poles, to catch the gun. They didn't have the money in the budget for another gun if it was lost in the river.
But the guns used in that movie were real guns, kept at all times in a locked gun locker (like a big tub with wheels) with only one person in the entire production having the combination and the keys to the locks (3 locks). On days where the guns weren't to be used, the entire locker was locked in a safe inside the prop truck (like a UPS delivery van, kinda). The prop master was the only one with access to the prop truck, but he didn't have access to open the gun locker.
