(^look at the second post)

The TSD SD97 is "supposed" to shoot at 550fps, but there are various videos where we can see it goes over 600fps..

YouTube - ‪TSD SD97 Chrono Test 2 (.2g Ammo Only)‬‏

It is considered a "controlled firearm" if it fired over 500 or more than some energy level, I am not sure which.
