So I’m pretty sure I saw this movie 8 years ago on Netflix. It’s in English and in color.

It starts in a small town apparently in the middle of nowhere. The main character is a grocery store clerk/stalker talking about how he started carrying a gun and how strong it makes him feel.  Somehow his friends also find guns and they have a shooting range in a mine. In the end the kids help an old woman cross the street and…there is a shootout all the kids die.  I also remember the main character falling in love with his gun…?
