I personally think that the tower needs a shooting range, like behind the gunsmith there's an indoor shooting range, and when you walk up to one of the booths it goes first person and you pull your gun out, you already have the gun on your back, and going first person to third person is pretty seamless when you use a d pad emotion while in first person. I think lots of people would like to try the gun(s) they have just decrypted, bought, or been rewarded without having to wait to go to a destination, or make a desperate trip to do so. It will keep the tower more busy too! You could say that part of the fun is having to wait till your next outside the tower free roaming, doing a mission or what have you to use your knew firearm and feel it's kick, but i much rather have a new thing to do in the tower. Plus the gunsmith is already selling ammo!! So maybe using the gun range could cost a little glimmer? Buy your own ammo
