The last assault weapons ban resulted in several new single stack pistols being developed. These actually turned out to be good for concealed carry. If, God forbid, another AWB passes (or if enough states follow N.Y. and pass anti-gun state laws) will new guns be developed in response? For example, single stack Glocks in all calibers. Or what if someone redesigned the1892 Winchester lever-action to feed modern semi-auto pistol cartridges like 9mm and 45acp? That would bypass all the magazine restrictions and make a nice little home defense carbine.
