How to make a gun not fall apart when placed in the workspace?

So whenever I take a weapon (Because I can't make my own) and I place them in the workspace, when they are picked up, the whole model floats around your character. Like all the parts come apart and just show up in random places near your player. Is there a script I can insert into them, or some way to avoid this?

Ozzypig's Talon Handler Weld Plugin should do the trick. You needed to weld the parts.
