First Person / 3rd person weapon hands animation

So since im a newbie in unity, im doing a singleplayer game (that later ill redo as multiplayer if i actually finish it and dont give up halfway) and i want to be able to be seen both FPS as 3rd person…the problem is, i have some characters modeled already and have some guns modeled already aswell …but how should i make the reload animations and the placement on the hands for each gun??

should i just animate each of my character to 1 reload animation PER wpn

i read somewhere that i could make floating hands animated per wpn and then make it so its only visible for the player and make it so its a special well animated FPS and a badly/non animated 3rd person

and how about the hand placement? is it enough just to make the hands parent of the gun and BAM??

sry about all this newbie questions but im actually an “okay” programmer, just dont know much about game design choices
