Very true. If they were useless the company would have gone under years ago. The only performance related drawback is that they are unreliable in some autos as the recoil energy is different than what the gun was designed for. Of course a revolver doesn't have this issue.
And I think that the only way you'd get one of these to a low velocity is to be a long ways away....
