I wouldn't worry about most guns on 007, since they no longer carry most of their inventory. Anyways, exact fps figures on guns can be spotty, typically there's a range of fps that a model of gun will fall into. Sometimes manufacturers include that information, sometimes they don't. Sometimes retailers bother posting that info, sometimes they don't. When in doubt, google for a review of the gun in question.
