Buy a used car and expect to replace the tires, brakes, exhaust ect. Buy a used gun and expect to have to deal with something. Maybe you will be lucky enough to get the one the previous owner "just didn't like".
It's a crap shoot sometimes.
Carrying two guns? Carrying two FULL SIZED guns? Well, if you can handle the all day pain the back, OK.
Does any one consider you paranoid? Who cares? They aren't living your life.
Have you ever considered moving away from St. Louis? I have lived in an area that became a high-crime area. I moved ASAP. Just food for thought.
If ranting on the internet helps get your thoughts straight, fine. We have all read dumber things than a man working out important issues like this.
Stay safe, grady.
