I read somewhere that in the movie the SHIELD agents will be packing plasma rifles similar to those in CA: TFA. In Thor they had no idea that they were dealing with an alien from another dimension, but in The Avengers the extraterrestrial nature of the threat will be apparent from the beginning. It makes sense that they would carry standard issue pistols when facing mere human threats and switch to the high tech gear when aliens invade.
