So one of my buddies is a cop. We were talking about how many rounds he carries. He's basically got 3 magazines. 1 in the gun and 2 spares. 13rnds each in the spares and 14 rounds in the gun. the gun is a .40 glock. is this a standard load? Do they ever carry more? I suggested that he keep at least an additional 2 mags at the ready in his patrol vehicle. Reasonable? I believe they have shotgun and ARs in their cars as well, but let's just keep it to his sidearm.
