EXPLANATORY NOTE 
Presidential Decree No. 1866, as amended, which codifies laws on firearms and 
explosives does not contain any 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 safety, 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.* 
’ This bill was re-filed during the Thirteenth Congress, First Regular Session.
