If you carry a gun have you ever needed to use it?

Following another post in cc I saw comments about people 'needing' to carry a gun and for their protection. I'm just curious if anyone has ever actually used it in an everyday situation? Has anything happened and you've thought 'I'm so lucky I had my gun on me'? Or has carrying a gun got you into trouble?
This isn't meant to offend anyone, I'm genuinely interested and trying to get a better understanding because it's so unheard of in the uk. No judging anyone who has used a gun for whatever reason either 🙂
