if i was a cop i would carry a back up. probably a compact 9mm with my main being a full size 9mm.

i like the idea of a back up specially if risking your life for others safety is part of your job duties. I can't say anything bad about wanting to carry a back up as when I had my AR... I had two. One was a back up... you know in case the zombies attack and I didn't have time to reload my magazine h:
