I only want to know that is it legal to use a fire arm issued for personal protection to be used for commercial use.
The gun is not being "used" for any commerial purpose by security guard. He is merely carrying it with him for self protection which anyone can always carry regardless whether he is security guard, doctor, engineer, lawyer, businessman, labourer, driver, waiter, worker, senior citizen, unemployed or whatever. He is not "using" it by carrying it. He will be "using" it when he pulls the trigger of his gun when the occasion demands for self protection/ social work as allowed by law . Hope it clarifies your query.
But why do we need license to armed ourselves?
Because those corrupt ruling over the ignorant people of this country can loot and their hard earned money can be siphoned into Swiss banks etc.
Those who framed the US Constitution knew all this naturally corrupt behaviour of rulers and therefore wrote the 2nd Amendment to safeguard one of the most important of human rights called RKBA so that people can actually protect their Constitution and all their rights guaranteed within it.
but it is opposite of what is happening in our Bharat the land of Mahatma.
Who wants to listen to Mahatma? Those in power only want to use his name to fool the people.
"Among the many misdeeds of the British rule in India, history will look upon the act depriving a whole nation of arms as the blackest." --M. K. Gandhi
“He who cannot protect himself or his nearest and dearest or their honor by non-violently facing death, may and ought to do so by violently dealing with the oppressor. He who can do neither of the two is a burden.”--M. K. Gandhi
"But I believe that nonviolence is infinitely superior to violence, forgiveness is more manly than punishment. Forgiveness adorns a soldier...But abstinence is forgiveness only when there is the power to punish; it is meaningless when it pretends to proceed from a helpless creature...."--M. K. Gandhi
Perhaps Jalinwabagh could have been averted if there was right to arms of Indian Citizen, and General Dyer would have laerned a Lesson.
Who wants to avert Jallianwala Baghs today? What kind of people are ruling over this country today? Will these kind of people ever want to give up the monopoly of power and violence that was in hands of General Dyer?

The figures in the above article translate into 4.33 citizens dying in custody per day! These figures do not include extra-judicial police killings so called "encounter killings". So even if we discount encounter killings and assume that all such custodial deaths were reported accurately, it basically means that you are 2.5 times more likely to be knocked off by the police (in custody) than by a licensed gun owner!
Do these statistics seem like they belong in a free country?
