Two quick points:

1. SAAMI was actually founded at the request of the federal govt. back in the '20s to promote standards for purposes of safety -- when firearm and ammunition quality was a lot more iffy than today.

2. I'd suggest we're better off with a private sector organization creating voluntary standards (even if they're a little inconsistent) than we'd be under a regime of government proof houses to which you must send your gun for "reproof" after modification...
