Nothing fancy, Springfield 9mm Pistol.
And yeah, my company knew about it. Yea, it was locked up, i had to buy a biometric pistol safe To keep it at work.
The CTO and myself had the key/biometric settings in the safe. No one else did.
It was in the server room, behind a key padlock and the ammo was in a locked (key) box inside the safe.
The server room was 20 feet from my desk.
