Here are some of my mom's that I have. I've posted these before. Cool toys for sure. Notice the belt buckle gun that shoots plastic bullets. We had a matching pistol and rifle set with turquoise stock and grips. I know I broke the rifle, I bet my grandmother has them stashed somewhere.
We had some pretty realistic looking cap guns when I was a kid. My grandparents kept some over at their house for us to play with when we visited.
A few years after my grandpa died, my grandmother was cleaning out the basement one day and found what she thought was one of our old toys. She held it up to look at it, and casually pulled the trigger. A bullet went past her ear and into the ceiling.
