One day as a kid I was swapping between channels and I remember about this scene where a guy tried to rob a pharmacy (or store/something alike), but he threatened the woman by putting his gun literally into her vagina, and I think he even shot it at the end… After or between that, there was a bunch of guys in the middle of a gunfire (which reminds me Scarface for some reason). Any ideas?
Going Places (1974)?
