sorry see A semiautomatic pistol that has the capacity to accept a detachable magazine or that may be
readily modified to accept a detachable magazine, if the firearm has one or more of the
following:
i. a threaded barrel;
iii. a shroud attached to the barrel or that partially or completely encircles the barrel,
allowing the bearer to hold the firearm with the non-trigger hand without being burned,
but excluding a slide that encloses the barrel;
iv. a flash suppressor;
v. the capacity to accept a detachable magazine at some location outside of the pistol
grip; or
vi. a buffer tube, arm brace, or other part that protrudes horizontally behind the pistol grip
and is designed or redesigned to allow or facilitate a firearm to be fired from the
shoulder.
