CrackPot in spirit we agree but the language does not support your hypothesis that rifle form of AW is OK but pistol form is not.
Sorry, but you're just flat-out wrong, and nobody should listen to your advice.
According to the black-and-white letter of the law of the "feature test" portion of the AWB, a post-ban AR-style rifle is fine as long as it doesn't have two or more of the "evil features" for a rifle.
Similarly, a post-ban pistol is fine as long as it doesn't have two or more of the "evil features" for a pistol. Note that the list of features for a pistol is different from that for a rifle.
The issue is that for pistols like Scorpions, AR pistols, MP5-style pistols, Sig MPX pistols, and others like them, they are basically guaranteed to run afoul of the feature test. As a reminder, here is the pistol feature test:
------
a semiautomatic pistol that has an ability to accept a detachable magazine and has at least 2 of--
(i) an ammunition magazine that attaches to the pistol outside of the pistol grip;
(ii) a threaded barrel capable of accepting a barrel extender, flash suppressor, forward handgrip,
or silencer;
(iii) a shroud that is attached to, or partially or completely encircles, the barrel and that permits
the shooter to hold the firearm with the nontrigger hand without being burned;
(iv) a manufactured weight of 50 ounces or more when the pistol is unloaded; and
(v) a semiautomatic version of an automatic firearm; and
------
A typical MP5-style pistol meets (i), (iii), (iv), and (v), so it's
definitely an AW according to the feature test.
