Is it possible to mount small caliber pistol or a light air soft that can be remotely controlled on a DJI drone? I am looking forward to doing this and which drone would be the best fit for the task?

You would be better off building your own, and you should probably check the legality of mounting anything others than airsoft or nerf, maybe paintball, but any actual firearm is probably illegal.

Well of course an actual firearm would be illegal in public but not if you are doing it in your basement.

Oh ... Thats rough

Good luck with that.  I'm getting visions of the 5park spinning around like a demented ED-209.

Where shall we send the flowers?

I hope you're not planning on doing something like this (it starts at around 0:57):
