Indians For Guns

Is this illegal in India to buy and keep airguns online from global sites?
I wanted to buy this- http://www.pyramydair.com/s/m/Crosman_C31/1589
If it is not illegal, then do I have to get a license for buying/keeping it?
If yes, please tell me the procedure to get a license and buy online. Please help.

There is plenty of information on the forums about what you are looking for. Would be nice if you would search before you directly ask for answers.
