You know, every photo that I have seen lately of Naval aviators with their handguns, they all had M11s.
Oh, and Army PSDs only carry M11s if they are in civvies. Every O-6 and up in Iraq has his own PSD, and since they are in DCUs, they are all carrying M9s. Likewise with CI agents (although most of them are being removed from tactical MI units, so they will be more likely to be out of uniform than in one). CID guys worked across the street from my original detention facility in Iraq, but I never really paid much attention to what they were carrying because we were having a small feud with them at the time over parking and other stupid crap.
