Where 'does' Niko put that rocket launcher?
You get guns from the boot of your car if loaded at your safe house, home or ware-house.
Some of the obvious things that stand out to me is that, in this fantastic game of GTA, the developers have gone into amazing detail with the vehicle handling physics, AI and scenery, yet still have you pulling a rocket launcher out of you back pocket. It actually looks like Niko pulls it out of his fly-zipper, big man, hey!
