We covered that in the linked discussion. Basically, the Judge and Governor have rifled barrels, so they’re judged to be different in that regard. Plus, they’re pistols, not something that could appear to a zealous prosecutor to be a sawed-off shotgun. Appearance, being what it is, puts the Shockwave at a disadvantage.
Would such a prosecutor in OK take up the issue if there was a legal case involving the use of a Shockwave in a self defense situation? Maybe not - but maybe.
