A priori, it is the firearm which is Prohibited/Non Prohibited for civilian possession and 'bores' or 'cartridges' or calibers are a posteriori.
Prohibited arms should not be confused or linked with prohibited bores. Any firearm can be prohibited arm but not of prohibited bore. Similarly any firearm can be of non prohibited bore but prohibited firearm. And speaking strictly from legal perspective, neither prohibited arms nor prohibited bores are in reality prohibited. The use of word "prohibited" in this matter is a misnomer, only the level of restriction varies.
the entire concept of PB/NPD is unnatural and untenable is also a matter of discussion.
Yes it is against the spirit and intention of the Constitution of India. Just like the 2nd Amendment of American Constitution which talks of armed people's militia, the same concept exists under our Constitution but in bit hidden manner. Arms are fundamental right of citizens under Article 19 and the exact corresponding fundamental duty of citizens(armed militia of citizens created by Article 19) is mentioned in Article 51A(c)&(d). During emergencies mentioned in Article 51A(c)&(d), manufacturing, supplying weapons and their ammunition of different bores will be a logistic nightmare.
i believe that MHA website do not contain such things for the public to see. hence RTI is needed.
We have a new Home Minister at MHA from today, let us all raise a grievance with MHA at http://pgportal.gov.in/
that all notifications that are in force under Arms Act 1959 are not published here http://mha.nic.in/uniquepage.asp?ID_PK=567
which every public authority under Section 4(2) of RTI Act 2005 is supposed to do. The copy Section 4(2) of RTI Act 2005 is produced below:
It shall be a constant endeavour of every public authority to take steps in accordance with the requirements of clause (b) of sub-section (1) to provide as much information suo motu to the public at regular intervals through various means of communications, including internet, so that the public have minimum resort to the use of this Act to obtain information.
