Note: Sheppard describes it as a "a nine millimetre, semi-automatic" in the second season episode "Duet". Thank you.

"Mystery" of why Atlantis uses M9s but not Zats[]
It is, of course, because if the Atlantis expedition had unlimited ammunition in the form of Zats, there would be no dramatic tension in Season 1 as to the limited supplies the expedition came from Earth with. I just felt it had to be said. RamblerReb (talk) (Contribs) 17:37, 28 June 2011 (UTC)
The Atlantis expedition uses it,because it's readily available in substantial quantities unlike the Zats,most of the armed personnel are already trained for it,and considering the amount of money the whole program swallows it's probably a pretty low priority to rearm every soldier/armed scientist with a slightly more effective sidearm,that's basically only used in combat as a last ditch weapon if everything else fails.And I doubt that most wraith would be able to keep charging at full speed with several 9mm rounds inside it's head/central nervous system.195.228.127.158 21:34, January 4, 2013 (UTC)
Oh, fine, think of an in-universe explanation, why don't you. Killjoy. ;) RamblerReb (talk) (Contribs) 00:09, January 5, 2013 (UTC)
