The 'Night Night' gun was Chekov'd in earlier when they were loading the plane. A project Fitzsimmons had been working on for a while. And then they showed them working on it earlier as a way to bring down Richards non-lethally. I dunno, it seemed like a macguffin that wasn't needed... Couldn't they have just used a taser or tranq dart guns? Those were also SHIELD issue in the comics, as I recall. It could be argued that they didn't know or think ordinary take down methods would work on Richards, with all those super-chemicals in his system.. but the same can be said for the Night Night Gun, plus the fact that it was completely untested and rushed to completion.
And as mentioned, Coulson had already done a very good job of talking Richards down, to the point he was pretty much about to turn himself in when Ward shot him. It seems necessary, and I really would have liked to seen Coulson dress Ward down for taking the shot when he didn't need to.
I do agree with other people though, that this show seems a very strong mix between Men in Black, X-files, NCIS and Warehouse 13, mixed together and dipped in Marvel Universe sauce. And I am totally okay with that, because I love all of those elements separately.
