Looking for advice on making faster magazine recharge and limb damage bonus perk

[Gauron]

Hello there!

Im in need of some advice or pointers on how could i make a perk that adds bonus limb damage to recharger weapons (Revontulet's Recharger Weapons Expansion) and increase the speed the recharge happens.

Soo far i can make the base perk but im not sure how to exactly make these two effects. I can increase the total damage but i dont know how to make it only affect limbs and i have absolutely no idea how to make them charge faster because the reload boost from what i heard only affects the reload animation which these weapons dont have.
