I'm not arguing with you so forgive me if it looks that way, I looked into deactivating a few tired run of the mill SXS guns a while back and thought anything with a pistol grip would look nice as a sawn off to hang on the wall but was put off the idea when I looked at the guidelines.
Saying that, it looks like the shortened barrel cert would cover it (providing it's altered before submitting) but the theatrical/training issue still seems to stop them being sold as wall hangers.
I may very well be wrong though.
Taken from the guidelines....
Any substantial alteration to a deactivated firearm (e.g. the shortening of shotgun barrels, or adaptation to allow the firing of blank cartridges or to operate as an air weapon) will render the deactivation certificate invalid. Although only a Court can provide a definitive ruling on the subsequent classification of the altered item, the automatic exemption from certificate control provided by Section 8 of the Firearms (Amendment) Act 1988 would no longer apply to the various component parts, unless the weapon is re-submitted to the Proof House for re-certification.
Sorry for going off topic with Tim's original post.
