Weapon Parenting v.3.0

I have about 30 weapons in my game. Most are axes and swords, the rest are spears. Is there a simple way to ensure that when I parent them to my model, that these weapons will align properly? I’ve been looking around on the internet as well as unity answers and still have yet to come up with a solution despite best efforts. If anyone could help I would be most grateful.

For each different weapon type (assuming different weapons require different alignments), parent an empty GameObject to the weapon hand and position/rotate that empty "mount point" into the perfect alignment for that weapon. Then when you Instantiate() your weapon objects, instantiate them at the position and rotation of the mount point, then parent them to the mount point.
