Well to be honnest I was not too impressed by my 85 combat, so I started thinking, more weight at the barrel.
So I though what about making the plastic pin for the reciol spring out of stainless, that should add some weight under my barrel
so I spend an afternoon behind my old taig lathe.

this gives me 11.3gram more weight, and I must say I like it, it gives me less 'snap' when firing the 85 combat and it makes it more accurate.
