Serious discussion. How to overcome the fear of gear failure.

I have been around guns abd shooting sibce i was 10. Im now 30. I currently have my ccw permit and need to re up it. I have recently been struggling through with the idea of equipment failing while carrying loaded. My firearms safety is top notch. i possess a good holster n regularly clean and practice with my firearm. I just can’t seem to shake the feeling of “ this is a piece of equipment and equipment can randomly fail” Does anyone else deal with this or am i just a pussy because it bothers me to a certain extent.
