To me, it's always been clear; 400fps limit is 400fps limit, no matter what shoots it. Why would there be any kind of distinction between rifle, smg, pistol, aeg or propane or CO2?
Most airsoft rifles are used from a longer distance, and pistols are mostly used in CQB and a much shorter distance.
So same power, but shorter distance=more damage=more dangerous. That's why most of the indoor games have limited the FPS to a much lower one.
