Where are you getting this 450 fps figure? Did you chrony this? KJW M9 typically shoots 300-320 fps with .2g BB. Most stock pistols are in the 280-320 fps range.

not cheap, don't use it unless you have to because your gun is too fragile etc.
Source has a lot of duster, but it's not 134a (tetrafluoroethane). It's really hard to find it and it generally not available to the public, as it's the stuff you can get high off of. The stuff that Source and other stores sell is trifluoroethane, and it's corrosive to rubber. Using that in an airsoft gun will eat your seals.
