EXPLANATORY NOTE 
Presidential Decree No. 1866 which codifies laws on firearm, or explosives does not 
contain a provision to make it unlawful for any person to manufacture, import, sell, ship, deliver, 
possess, transfer, or receive firearms that are not detectable by metal detectors used by police and 
military authorities. 
The manufacture, importation and sale of such undetectable firearms contribute to the 
ever increasing crime rate in the country. If these undetectable firearms will not be prohibited, 
metal detectors, more particularly those being used in airports for public security and safely, will 
be of no purpose at all. 
This bill seeks to reduce if not totally eliminate the crimes and the resulting deaths and 
injuries through the use of such undetectable firearms.
