Realistically Lightweight PFM-1s addon

Have you ever wondered why something that weighs more than an RGD-5 or F1 grenade is way weaker than either and is often not enough to kill Stalkers? Maybe not, but I did. And why does something that is largely made of plastic heavier than metal anyways? So I looked into it and found out that we've all been suffering an oopsie. PFM-1s in game weigh 0.75kg, while the real deal only weighs 75 grams - 1/10th the weight! Someone forgot to add that extra zero, and we've been copying that mistake ever since! How many years have we lived this lie?

Today, I'm changing that, and I hope everyone else does from now on. Butterflies with this simple edit now weigh only 0.075, no longer being the weighted nuisance they once were. Now you can easily carry enough around to hotbar & lay down enough of them to do some actual damage. May this error be corrected once and for all.
