Firing your weapon as an officer or detective is quite rare. The interviewer would like to know if you have had to do so in the past, the circumstances, and the result. If you have fired your weapon, you will likely have supporting documentation. Take that with you to your interview, if possible.

If you have had to fire your weapon: "I have fired my weapon just once in my career. It was during a robbery, and the suspect fired his weapon at my partner. I am happy to have you review the case file and all supporting documentation."

If you have not had to fire your weapon: "I have never fired my weapon, I am happy and very thankful to say. However, if the situation occurred, I would be confident in my ability to react appropriately."
