I am very new at this, as I just got my concealed pistol license; however, just having a gun in the car has had a HUGE positive affect on me. I was driving to the range the other day, gun basically inaccessible in the trunk, when another driver behaved like a **** and their passenger flipped me off. In my younger days I would have probably behaved poorly, but just having a gun in my car made me de-escalate ASAP. I let the other guy get ahead of me as quickly as possible and I never made eye contact. Rather than being upset about it, I realized immediately the positive behavior that carrying a gun forced on me - it's a responsibility.
